Java program: Standard Deviations

Instructions:

Write a program to input exactly 15 doubles, then calculate the mean and the standard deviation for those numbers, then to output the mean and the standard deviation, then to output each number followed by its number of standard deviations from the mean.

To calculate the standard deviation:

-Calculate the mean Calculate the sum of the squares of the difference of each number from the mean.

-Divide that by the number of elements (15).

-Take the square root of that.

Example output:

Enter a score: 67

Enter a score: 75

Enter a score: 80

Enter a score: 99

Enter a score: 50

Enter a score: 92

Enter a score: 83

Enter a score: 85

Enter a score: 87

Enter a score: 77

Enter a score: 72

Enter a score: 69

Enter a score: 55

Enter a score: 73

Enter a score: 76
