In this problem, we explore the effect on the standard deviation of adding the same constant to each data value in a data set. Consider the following data set.7, 7, 15, 9, 17
(a) Use the defining formula, the computation formula, or a calculator to compute s. (Enter your answer to one decimal place.)
(b) Add 6 to each data value to get the new data set 13, 13, 21, 15, 23. Compute s. (Enter your answer to one decimal place.)
