Answer 1

The following are the formulas to find mean and standard deviation of numbers.

To compute deviation with this formula, you have to store the individual numbers using an (one-dimensional) array, so that they can be used after the mean is obtained.

Your program should contain the following functions:

// Compute the mean of an array of double values

double mean(const double x[], int size);

// Compute the deviation of double values

double deviation(const double x[], int size) ;

Write a test program that prompts the user to enter 10 numbers and displays then mean and deviation
