Using Python Code,

Please let me know if you have any questions, Thanks in advance!

Part B. The standard deviation (o) of a large set of n data points is defined as follows: 0 = > (Xi 2 Write Python code to calculate and display the standard deviation of the set of grades given. Note that 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
