Exam Scores

Statisticians use the concepts of mena and standard deviaiton to describe a collection of data. The mean is the average value of the items, and the standard deviaiton measures the spread of dispersal of the njmbers about the mean. Formally, if x1,[login to view URL],...,xn is a colleciton of date, then mean= m= x1+x2+x3+...+xn /n standard deviaiton=s=(square root)(x1-m)squared + (x2-m)squared + (x3-m)squared +...+ (xn-m)squared /n-1 Write a computer program to (a) Place the exam scores 59,60,65,75,56,90,66,62,98,72,95,71,63,77,65,77,65,50,85, and 62 into an array. (b) Calculate the mean and standard deviation of the exam scores. (c) Assign leter grades to each exam score, ES as follows: ES greater than or equal to m + 1.5s A m + .5s less than or equal to ES < m + 1.5s B m - .5s less than or equal to ES < m + .5s C m - 1.5s less than or equal to ES < m - .5s D ES ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
