Activity #2: Statistics Using Lists of Data-Team Activity There are two files posted to get you started with this activity: Grade Date_LabbAct2.py - Python file with a list defined representing grade data Lab6 Act2 Grade Data.xlsx - Excel spreadsheet with the same grade data The activities below require you to perform some simple statistical analyses on the given data. The end result should be a Python code that produces the correct results, but you may use Excel to check your verify your methods and to check the answers for correctness. Please put the code for the following Activity #2 exercises in the same file (Lab6_Act2.py). Please separate code for each part with appropriate comments. Develop Python code to produce the results described for each part below. Part A. The mean (*) of a set of n data points is defined as follows: (x + xy +.....+x.)_1 Write Python code to calculate and display the mean grade of the set of grades given. Please do not use any built-in Python functions for summing or calculating the mean. Instead, set up a loop to calculate the sum of the numbers in the list, then divide by the number of items in the list. Use Excel to verify your results. Part B. The standard deviation (a) of a large set of n data points is defined as follows: (xi-*) Write Python code to calculate and display the standard deviation of the set of grades given. Note that x in the equation above is the mean of the data from Part A. Please do not use any built-in Python functions for calculating o. Instead, set up a loop to calculate the required summation, then perform the final calculations. Use Excel to verify your results. Part C. Write Python to find the minimum and the maximum grade in the set of grades given. Once again, please do not use built-in functions. Instead, use your knowledge of lists and list indices, loops and if-elif-else blocks to find and display these two values. Use Excel to verify your results. Part D. You are a kind-hearted instructor that wants to raise the average grade for your class. Write Python code to determine the constant deltaGrade that must be added to each student's grade for the class average to be exactly 75.0. . You may allow some student grades to exceed 100.0 for this exercise
