Question

1) For the sample shown below, determine the mean and standard deviation. Use the basic (or defining) formula to compute standard deviation. Then find the Coefficient of Variation of this data set. Xi Xi - X 33 27 32 35 28 (Xi - X)$^2$ Now recompute the sample standard deviation using the shortcut (or computing) formula. Xi X$i^2$ 33 27 32 35 28
