Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are x 1 ,   x 2 ,   x 3 ,   x 4 , and  x 5 , then the mean is x = ( x 1 + x 2 + x 3 + x 4 + x 5 ) / 5 and the standard deviation is:

s = ( x 1 − x ) 2 + ( x 2 − x ) 2 + ( x 3 − x ) 2 + ( x 4 − x 2 ) + ( x 5 − x 2 ) 5

Your program must contain at least the following functions: a function that calculates and returns the mean and a function that calculates the standard deviation.
