15. a. After 6 points have been added to every score in 70 and the a sample, the mean is found to be M standard deviation is s = for the mean and standard deviation for the original sample? b. After every score in a sample is multiplied by 3, the mean is found to be M deviation is s = 13. What were the values 48 and the standard 18. What were the values for the mean and standard deviation for the original sample? 11. For the following sample ofn 6 scores: 0, 11, 5, 10, 5, 5 a. Sketch a histogram showing the sample distribution. b. Locate the value of the sample mean in your sketch, and make an estimate of the standard deviation (as done in Example 4.6). c. Compute SS, variance, and standard deviation for the sample. (How well does your estimate compare with the actual value of s?)
