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. 15, 9, 7, 17, 11 (a) Use the defining formula, the computation formula, or a calculator to compute s. (Enter your answer to one decimal place.) (b) Add 2 to each data value to get the new data set 17, 11, 9, 19, 13. Compute s. (Enter your answer to one decimal place.)
