Please Help me

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 computer 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. The results are displayed in the following form: Grades between 0 and 19 2 students Grades between 20 and 39 4 students Grades between 40 and 59 6 students and so on.

Solution

Excecutable code is:

%Start the script

%array of given scores

N019=0;N2039=0;N6079=0;80100=0;

N=length(x);

For i=1:30

If x(1)>=0 && x(i)<=19

N019=N019+1;

End

If x(i)>=20 && x(i)<=39

N2039=N2039+1;

End

If x(i)>=40&&x(i)<=59

N4059=N4059+1;

End

If x(i)>=60&&x(i)<=79

N6079=N6079+1;

End

If x(i)>=80&& x(i)<=100

N80100=N80100+1;

End

End

Fprintf(‘grades between 0 and 19: %6.2f students\ ’,N019)

Fprintf(‘grades between 20 and 39: %6.2f students\ ’,N2039)

Fprintf(‘grades between 40 and 59: %6.2f students\ ’,N4059)

Fprintf(‘grades between 60 and 79: %6.2f students\ ’,N6079)

Fprintf(‘grades between 80 and 100: %6.2f students\ ’,N80100)

Matlab output

Grades between 0 and 19: 2.00 students

Grades between 20 and 39: 5.00 students

Grades between 40 and 59: 6.00 students

Grades between 60 and 79: 7.00 students

Grades between 80 and 100: 10.00 students
