Textbook Question
Chapter 6, Problem 24P
A list of exam scores (S) (in percent out of 100% is given: 72, 81, 44, 68, 90, 53, 80, 75, 74, 65, 50, 92, 85, 69, 41, 73, 70, 86, 61, 65, 79, 94, 69. Write a computer program that calculates the average (Av) and standard deviation (Sd) of the scores, which are rounded to the nearest integer. Then, the program determines the letter grade of each of the scores according to the following scheme:
Score% | S=Av+1.3Sd | Av+ 0.5Sd=S
|
Letter grade | A | B |
Score% | Av-1.5Sd=S
Av-1.3Sd=S
|
|
Letter grade | C | D |
Score% | S
|
|
Letter grade | F |
The program displays the values of Av and Sd followed by a list that shows the scores and the corresponding letter grade (e.g., 72% Letter grade C).
