A program that solves 10 student grades, finds the average, the standard deviation, and the grade for each of the 10 students. Based on the following. 1 times the standard deviation below the average = F 0.5 - 1 standard deviation below the average = D < 0.5-1 standard deviation below or above the average = C 0.5 - 1 standard deviation above average = B > 1 times the standard deviation above the average = A

Must use the following functions:

ListData(scores) Reads in values from the keyboard into the list

average(scores) Calculate the mean of a list

standardDeviation(scores, mean) Calculate the standard deviation on array given its values and its mean

LetterGrade(score, mean, stdDev) Calculate a letter grade based on a score, a mean and standard deviation
