Four weekend Programming classes consist of students with the following numbers: Class I=32 students, Class II=40 students, Class III=34 students and Class IV=28 students. The distribution of students' average marks for each class for four (4) tests is given as the followings: Test1 = [76 78 68 82] Test2 = (58 65 70 66] Test3 = [82 84 75 90] Test4 = [77 68 69 75] From the above distribution, write a Matlab/Octave script (m-file) that able to compute the followings: a) b) c) Total student marks for Test1. Highest average mark for Test 3. Which classes have Test 4 average mark higher than their Test 2. Write your m-file script here
