a. After 3 points have been added to every score in a sample, the Mean is found to be M = 83 and the standard deviation is s = 8. What were the values for the mean and standard deviation for the original sample? b. After every score in a sample has been multiplied by 4, the mean is found to M = 48 and the standard deviation is s = 12. What were the values for the mean and standard deviation for the original sample? Solution a) Mean = 83-3 = 80 stdev didnt change = 8 b) mean = 48/4 = 12 stdev will chang eby factor of 2 so s = 6.

a. After 3 points have been added to every score in a sample, the Mean is found to be M = 83 and
the standard deviation is s = 8. What were the values for the mean and standard deviation for the
original sample?
b. After every score in a sample has been multiplied by 4, the mean is found to M = 48 and the
standard deviation is s = 12. What were the values for the mean and standard deviation for the
original sample?
Solution
a) Mean = 83-3 = 80
stdev didnt change = 8
b) mean = 48/4 = 12
stdev will chang eby factor of 2 so s = 6

a. After 3 points have been added to every score in a sample, the Me.pdf

  • 1. a. After 3 points have been added to every score in a sample, the Mean is found to be M = 83 and the standard deviation is s = 8. What were the values for the mean and standard deviation for the original sample? b. After every score in a sample has been multiplied by 4, the mean is found to M = 48 and the standard deviation is s = 12. What were the values for the mean and standard deviation for the original sample? Solution a) Mean = 83-3 = 80 stdev didnt change = 8 b) mean = 48/4 = 12 stdev will chang eby factor of 2 so s = 6
