slove with matlab

(1) The following vector represents the distribution of final scores in a course: G=[68,83,61,70,75,82,57,5,76,85,62,71,96,78,76,68,72,75,83,93] Write a MATLAB code to determine how many times the final scores are above 75: (a) Using for loop. (b) Using while loop. (2) A list of 30 exam scores is: 31,70,92,5,47,88,81,73,51,76,80,90,55,23,43,98,36,87, 22,61,19,69,26,82,89,99,71,59,49,64. Write a MATLAB program that determines how many grades are between 0 and 19 , between 20 and 39 , between 40 and 59 , between 60 and 79 , and between 80 and 100 . In the program while loop and if statement should be used. The results should be displayed in a table form showing the number of grades in each range
