Matlab problem

I finished problem D. I am working on problem E, but error occurs. I wanna get table like below table. How to input my column variable Student_No, test1,test2,test3,and final percentage

4.2 Load the file thermo scores.dat provided by your instructor, or enter the matrix below and name it thermo_scores. (Enter only the numbers.) (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.
