Q1. 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 the grades as elements of a vector. The program then calculates the required quantities using MATLAB's built-in functions length, mean, and std. The results are displayed in the Command Window in the following format: There are XX grades." where XX is the numerical value. The average grade is XX." where X0X is the numerical value rounded to the nearest tenth "The standard deviation is XX." where XX is the numerical value rounded to the nearest tenth. Erecute the program arteolowine erades: 93, 7, 51 6299,41,82,7, 71, 68, 100. 46, 78, 80, and 83
