Chapter 4, Problem 7P
Write a MATLAB program in a script file that calculates the average and the standard deviation of a list of grades as well as the number of grades on the list. The program asks the user (input command) to enter (he grades as elements of a
“There are XX grades.” where XX is the numerical value.
The average grade is XX, where XX is (he numerical value rounded to the nearest tenth.
The standard deviation is XX” where XX is the numerical value rounded to the nearest tenth.
Execute the program and enter the following grades: 93, 77, 51, 62, 99, 41, 82, 77, 71, 68, 100, 46, 78, 80, and 83.
