by 3, what would be the new values for the mean and standard deviation? 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? After every score in a sample has been multiplied by 4, the mean is found to be M = 48 and the standard deviation is s = 12. What were the values for the mean and standard deviation for the original sample? For the following sample of n = 4 scores: 82, 88, 82 and 86: Simplify the arithmetic by first 80 points from each score to obtain 2, 8, 2 and 6 Then, compute the
