In this problem, we explore the effect on the standard deviationof multiplying each data value in a data set by the same constant.Consider the data set 11, 9, 4, 6, 6. (a) Use the defining formula,the computation formula, or a calculator to compute s. (Round youranswer to one decimal place.) s = (b) Multiply each data value by 7to obtain the new data set 77, 63, 28, 42, 42. Compute s. (Roundyour answer to one decimal place.) s =
