Compute the mean and standard deviation for the following sample of n = 5 scores: 70, 72, 71, 80, and 72. Hint: To simplify the arithmetic, you can subtract 70 points from each score to obtain a new sample. Then, compute the mean and standard deviation for the new sample. Finally, make the correction for having added 70 points to each score to find the mean and standard deviation for the original sample.
