can anyone help me write a script for this.

If you use the MATLAB function rand(1), it generates a random number between 0 and 1. That is, if yop use the command xerand(1) then x is a random number between 0 and 1, and every time it is called, x would be a different random number. (a) Use a "for loop" and the function rand(1) to create a vector x(n) with 500 elements. Then compute the average value of the elements in x. (b) Use another "for loop" and rand(1) to create a vector y(n) of 500 random numbers between the numbers -2 and +2
