Exp22 Excel Ch09 CumulativeAssessment Variation Tips

Excel Chapter 9 Cumulative Assessment – Variation Tips

Project Description:

Your friend Julia is a server at a restaurant. She downloaded data for her customers’ food and beverage purchases for the week. You will complete the workbook by applying consistent formatting across the worksheets and finalizing the weekly summary. The restaurant requires tip sharing, so you will calculate how much he will share with the beverage worker and the assistant 

Start Excel. Download and open   the file named Exp22_Excel_Ch09_CumulativeAssessment_Variation_Tips.xlsx.   Grader has automatically added your last name to the beginning of the   filename.
 

  The Excel workbook contains circular references. When you open the file, an   error message displays. This error will be resolved as part of the project.

The Tip Left column in the   Friday worksheet contains a fill color and number formatting. You want to   fill these formats to the other daily worksheets.
 

  Group the Friday through Monday worksheets, starting with the Friday   worksheet. Fill the format only for the range E5:E24.
 

  Hint: The Home tab contains the Fill option.

Now you want to insert column   totals for the five worksheets simultaneously.
 

  With the worksheets still grouped, insert SUM functions in the range B25:E25   and apply the Total cell style. Ungroup the worksheets.
 

  Hint: The Home tab contains Cell Styles.

The Week worksheet is designed   to be a summary sheet. You want to insert a hyperlink to the Total heading in   the Monday worksheet.
 

  On the Week worksheet, in cell A5, insert a hyperlink to cell A25 in the   Monday worksheet with the ScreenTip text Monday’s Totals. Test the hyperlink to ensure   it works correctly.
 

  Hint: The Insert tab contains the option to insert a hyperlink.

In cell A6 on the Week   worksheet, insert a hyperlink to cell A25 in the Tuesday worksheet with the   ScreenTip text Tuesday’s Totals. Test the hyperlink to ensure it works correctly.

In cell A7, insert a hyperlink   to cell A25 in the Wednesday worksheet with the ScreenTip text Wednesday’s   Totals. Test   the hyperlink to ensure it works correctly.

In cell A8, insert a hyperlink to   cell A25 in the Thursday worksheet with the ScreenTip text Thursday’s   Totals. Test   the hyperlink to ensure it works correctly.

In cell A9, insert a hyperlink   to cell A25 in the Friday worksheet with the ScreenTip text Friday’s   Totals. Test   the hyperlink to ensure it works correctly.

Now, you are ready to insert   references to cells in the individual worksheets. First, you will insert a   reference to Monday’s Food Total.
 

  In cell B5 on the Week worksheet, insert a formula with a 3-D reference to   cell B25 in the Monday worksheet. Copy the formula to the range C5:E5.

The next formula will display   the totals for Tuesday.
 

  In cell B6, insert a formula with a 3-D reference to cell B25 in the Tuesday   worksheet. Copy the formula to the range C6:E6.

In cell B7, insert a formula   with a 3-D reference to cell B25 in the Wednesday worksheet. Copy the formula   to the range C7:E7.

In cell B8, insert a formula   with a 3-D reference to cell B25 in the Thursday worksheet. Copy the formula   to the range C8:E8.

In cell B9, insert a formula   with a 3-D reference to cell B25 in the Friday worksheet. Copy the formula to   the range C9:E9.

Now you want to use a function   with a 3-D reference to calculate the totals.
 

  In cell B10 on the Week worksheet, insert the SUM function with a 3-D   reference to calculate the total Food purchases (cell B25) for the five days.   Copy the function to the range C10:E10.

The servers are required to   share a portion of their tips with the Beverage Worker and Assistants. The   rates are stored in another file.
 

  Open the Exp22_Excel_Ch09_CumulativeAssessment_Variation_Rates.xlsx   workbook. Go back to the Exp22_Excel_Ch09_CumulativeAssessment_Variation_Tips.xlsx   workbook. In cell F5 of the Week worksheet, insert a link to the Beverage   Worker Tip Rate (cell C4 in the Rates workbook) and multiply the rate by the   Monday Drinks (cell C5). Copy the formula, select the range F6:F9, and then   use Paste Formulas.
 

  Note: The tip is a monetary value in the Week worksheet. It should be   formatted for Accounting Number Format.

Next, you will calculate the   tips for the assistant.
 

  In cell G5 in the Tips workbook, insert a link to the Assistant Tip Rate   (cell C5 in the Rates workbook) and multiply the rate by the Monday Subtotal   (cell D5). Copy the formula, select the range G6:G9, and then use Paste   Formulas. Close the Rates workbook.
 

  Note: The tip is a monetary value in the Week worksheet. It should be   formatted for Accounting Number Format.

You noticed a circular error   when you first opened the Tips workbook. Now you will find and correct it.
 

  On the Week worksheet, check for errors and correct the formula with the   circular reference.
 

  Hint: The Formulas tab contains an option to find circular references.

You want to consolidate the   daily averages on the Week worksheet.
 

  On the Week worksheet, select cell J4. Use the Consolidate tool to   consolidate data from the daily worksheets. Select and add the range H4:I8 in   each of the daily worksheets. Use the top row and left column labels when   consolidating data. After consolidating the data, use Cut and Insert Cut   Cells to cut the weekday column labels and data to arrange them in order,   starting with Monday.
 

  Hint: Consolidate is on the Data tab.

You want to format the headings   in the consolidated area.
 

  Select the range K4:O4 and apply bold. Change the width of column M to 11.

You want to create a validation   rule to prevent the user from accidentally entering a negative value. For   now, you will create a validation in the Friday worksheet.
 

  Select the range E5:E24 in the Friday worksheet, create a validation rule to   allow a decimal value greater than or equal to zero. Enter the input message   title Tip   and the input   message Enter the amount of tip. (including the period). Use the Stop alert with   the error alert title Invalid Number and the error alert message The tip must   be zero or more.   (including the period). Test the data validation by attempting to enter -20 in cell E5 and then cancel the   change.

Now you will copy the validation   settings to the other daily worksheets.
 

  Copy the range E5:E24 in the Friday worksheet. Group the Monday through   Thursday worksheets, select the range E5:E24, and use Paste Special   Validation to copy the validation settings.
 

  Hint: The Paste Special dialog box contains the Validation option.

You want to unlock data-entry   cells so that the user can change the tips in the daily worksheets.
 

  Group the Monday through Friday worksheets. Select the ranges E5:E24 and   unlock these cells.
  Hint: The Home tab contains the option to unlock cells.

Now that you unlocked data-entry   cells, you are ready to protect the worksheets to prevent users from changing   data in other cells. Individually, protect each daily sheet using the default   allowances without a password.
 

  Hint: The shortcut menu from the worksheet tab contains the option to protect   the sheet.

The Template worksheet displays   #DIV/0! for cells containing the AVERAGE function. You want to prevent the   error from displaying if no data is entered.
 

  Display the Template worksheet. In each cell in the range I5:I8, nest the   existing AVERAGE function within an IFERROR function. Type 0 in the Value_if_error argument.

Hide the Template worksheet.

Mark the workbook as final.
 

  Note: Mark as Final is not available in Excel for Mac. Instead, use Always   Open Read-Only on the Review tab.
 

  Hint: The File tab contains the option to mark the workbook as final.

Close Exp22_Excel_Ch09_CumulativeAssessment_Variation_Tips.xlsx. Exit   Excel. Submit the file as directed.

This lab will be different. Your only task is to create a single page* document called an executive summary. An executive summary simply summarizes a report. Some would say it’s an executive summary because it allows executives to not have to read the entire report, but that would be pessimistic. 🙂 You could also consider it an executive summary because it summarizes the execution of a plan, and that’s a great way keep in mind what it should do. You need to create a single page report on why your hypothetical organization needs a security policy, and this executive summary should do two things:

1) Allow an executive that has to approve your plan to understand why it’s so important without having to understand all the things you learned over the course of the semester. You have to let them know enough to convince them without burying them in details. This is why Chapter 12 is helpful in framing the ‘why’.

2) You have to let them know how you’re going to do it with a broad outline of the structure of the Security Policy and who and how it applies to in the organization. These are the logistics behind the “who/what/where/when/how” elements all executives have to reconcile to the larger organizational issues they are responsible for.

The document should be one page with standard margins, single spaced, and well formatted. Your instructor reserves the right to determine any specific elements they wish you to follow in this assignment.

*Why is it a single page? Partly because you rarely have a lot of time to convince an executive of the technical importance of what you do before they feel overwhelmed by the ‘techie’ factor. The other part is because this is a skill you must develop; beyond your technical skills, some of the most important and valuable skills you have are ‘soft skills’ which are ironically ‘hard’ to find for employers and ‘hard’ to master for employees. Being able to succinctly explain technical issues to the people in charge without resorting to “trust me” is a very marketable skill

Which blockchain technology do you believe will survive and become the defacto industry standard, not as a crypto-currency but as a security-based technology. Why?

The registrar’s database of rooms, students, and courses is stored in three data structures:all_rooms is a dictionary that contains one pair for each classroom at Wassamatta U. The key is the room’s name (a string); the value is the room’s capacity (an integer).all_courses is a list in which each element represents one course offered at Wassamatta U. These elements are dictionaries called “course records.” Each course record has five keys, which are always named course id, name, time, room, and credits. The corresponding values can be different for each course record. They are:course id: the unique course ID (an integer)
name: the full course name (a string)
time: the time slot in which the course meets (a string)
room: the name of the room in which the course meets (a string)
credits: the number of credits for the course (an integer)
all_students is a dictionary that contains one pair for each student enrolled at Wassamatta U. The key is the students’s unique ID number (an integer), and the value is a list of course IDs (integers).It is fine for you to use these data structures in the body of your functions even though they are not passed in as arguments.What You Need to Do
Here are the functions you will need to ensure work correctly:total_rooms()This function should return the total number of classrooms at Wassamatta U. Fortunately, IT was able to recover the code for this function, so you will not need to reimplement it.total_courses()This function should return the total number of courses offered at Wassamatta U.total_students()This function should return the total number of students enrolled at Wassamatta U.room_exists(capacity)This function should return True if there is a room with exactly this capacity at Wassamatta U. and False otherwisestudent_is_enrolled(student_id)This function should return True if a student with student ID number student_id is enrolled at Wassamatta U, and False otherwise. Fortunately, IT was able to recover the code for this function, so you will not need to reimplement it.course_is_offered(course_name)This function should return True if a course with this name is ***** ***** Wassamatta U. and False otherwise.biggest_room()This function should return the name of the room with the largest capacity.total_courses(student_id)This function takes as an argument a student ID number. It should return the total number of courses the student with that student ID number is ***** enrolled in.total_credits(student_id)This function takes as an argument the student ID number of a student in the dictionary students. It should return the total number of credits for the courses in courses the student with that student ID number is ***** enrolled in.check_conflict(course_id1, course_id2)This function takes two course ID numbers as arguments. It should return True if the courses meet in the same room at the same time, and False otherwise (i.e., if they meet in different rooms or at different times).Note: Two time slots overlap only if and only if they are identical as strings.check_all_conflicts()This function should return True if any two distinct courses meet in the same room at the same, and False otherwise.check_over_capacity(course_id)This function should return True if the number of students enrolled in the course with course ID number course_id is equal to or less than the capacity of the room in rooms_list in which the course meets, and False otherwise.Hints: Some of these functions require you to do the same subtasks. We recommend writing them in the order listed. You will find that some of the later functions build on the earlier ones. When you recognize that you are doing something similar to something you have already done, you could:Copy your code from the old function into the new one and make appropriate changes.
Call the old function from the new function.
