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 5, 4, 15, 16, 17.
(a) Use the defining formula, the computation formula, or a
calculator to compute s. (Round your answer to one decimal
place.)
s =
(b) Multiply each data value by 5 to obtain the new data set 25,
20, 75, 80, 85. Compute s. (Round your answer to one
decimal place.)
s =
