In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. Consider the data set 4, 10, 10, 4, 6. (a) Use the defining formula, the computation formula, or a calculator to compute s. (Round your answer to one decimal place.) s
