In MATLAB:

Student No. Test 1 Test 2 Test 3 92 After loading it to MATLAB or manually enterting into MATLAB, please find the followings- (a) Extract the scores and student number for student 5 into a row vector named student_5. (b) Extract the scores for Test 1 into a column vector named test_1. (c) Find the standard deviation and variance for each test. (d) Assuming that each test was worth 100 points, find each student's final total score and final percentage. (Be careful not to add in the student number.) (e) Create a table that includes the final percentages and the scores from the original table. (f) Sort the matrix on the basis of the final percentage, from high to low (in descending order), keeping the data in each row together. (You may need to consult the help function to determine the proper syntax.)
