Python Project
Task 1 (50 points): (Intro to Data Science: Survey Response Statistics) Twenty students were asked to rate on a scale of 1 to 5 the quality of the food in the student cafeteria, with 1 being “awful” and 5 being “excellent”. Place the 20 responses in a list. 1, 2, 5, 4, 3, 5, 2, 1, 3, 3, 1, 4, 3, 3, 3, 2, 3, 3, 2, 5 Write a program that does the following: (a) Determine and display the frequency of each rating. (b) Use the built-in functions, statistics module functions and NumPy or Panda functions cov ered in the course materials to display the following response statistics: minimum, maximum, range, mean, median, variance and standard deviation. (c) Display a bar chart showing the response frequencies and their percentages of the total responses. Grading Rubric – 10 points for defining functions. – 15 points for finishing Task1(a)-(c). – 5 points for appropriate comments. – 10 points for a runnable python program with correct data visualization. – 10 points for screenshots of the program. Task 2 (50 points): (Classification with k-Nearest Neighbors and the Digits Dataset) Read the file “09-02-MachineLearning.pdf” and the python program “CaseStudy1.py” to learn the algorithm of k-Nearest Neighbors with the Digits dataset for recognizing handwritten digits. Re-write the python program by doing the following subtasks: (a) Write code to display the two-dimensional array representing the sample image at index 24 and numeric value of the digit the image represents. (b) Write code to display the image for the sample image at index 24 of the Digits dataset. (c) For the Digits dataset, what numbers of samples would the following statement reserve for training and testing purposes? X train, X test, y train, y test = 1 train test split(digits.data, digits.target, random state=11, test size=0.60) 2 (d) Write code to get and display these numbers. (e) Rewrite the list comprehension in snippet [50] using a for loop. Hint: create an empty list and then use the built-in function “append”. Grading Rubric – 15 points for finishing Task2(a)-(e). – 5 points for appropriate comments. – 20 points for a runnable rewritten python program – 10 points for screenshots of the program.

discussion question
Hello,
please am looking for someone to help me with this discussion question.. thanks
INTERNSHIP AT THE RAM & SONS AUTO INC
Each week you are to enter content into an online journal provided in Blackboard that briefly summarizes (1) the tasks you performed during your internship that week and (2) total hours worked with days/times. The content can be brief and in outline form and use bullet or another list styling, but keep in mind that this content will form the basis of the two major papers that you will write for this course. Therefore, the more detailed you are in your weekly journal, the easier it will be to finish the two papers. Specifically, your weekly journal should contain:
• The days and times you worked that week, as well as the total hours, worked. (Provide this information at the top of each weekly section so this will act as a de facto heading to separate each weekly entry that you make.)
• The skills or skillsets used/required to complete each task
• Each task you performed along with a brief description of what you did.
• A brief explanation of why the task needed to be done.
• Was there an outcome? If so, what was that outcome?
• What new terminology did you learn this week? Provide the term and its definition.

QUESTION 15
- Use solver to answer the following question: A manufacturing concern wishes to minimize its shipping costs between its 4 factories and 3 warehouses. Factory 1 supplies 1000 units per week and costs $5, $3, and $4 to ship each unit to Warehouses 1, 2, and 3 respectively. Factory 2 supplies 1200 units each week and costs $4, $3, and $3 to ship to Warehouses 1, 2, and 3. Factory 3 supplies 1500 units and costs $6, $2, and $5 to ship to the three warehouses. Factory 4 supplies 1800 units and costs $6, $2, and $4.
If Warehouse 1 requires 3000 units per week, Warehouse 2 demands 1000, and Warehouse 3 demands 1500, what is the minimum it would cost them in shipping to fulfill each warehouse’s demand?
