3- I need octave program for that question please, thank you

Question 3 Consider the marks of 8 students in Project scenario: 10, 6.7, 13.7, 12, 11, 10.7, 9, 11.2. The AVERAGE marks of the class is 10.54. Write a small program in Octave that sets a variable MEAN to 10.54 then asks the user to input the students' marks, and then prints the VARIANCE of the numbers. You must use a for loop and the commands: input() and printf() or disp()
