15, 13, 8, 12, 15, 17, 14, 9, 11, 16
Part A. Find the range, mean, median, and mode of Mike's scores. Show your work. (4 points)


range=17-8=9 mean=add all numbers=130 divide by how many numbers there are=10 130/10=13
medium=15,17 mode=15

How would a score of 30 affect the range, mean, median, and mode of Mike's scores?






b. If Mike could add 5 points to every game's score, how would it affect the mean, median, and standard deviation of his scores?
