Question

Transcribed Image Text: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 12, 14, 10, 4, 14.
In USE SALT
(a) Use the defining formula, the computation formula, or a calculator to compute s. (Round your answer to four decimal places.)
S =
(b) Multiply each data value by 8 to obtain the new data set 96, 112, 80, 32, 112. Compute s. (Round your answer to four
decimal places.)
S =
(c) Compare the results of parts (a) and (b). In general, how does the standard deviation change if each data value is multiplied
by a constant c?
O Multiplying each data value by the same constant c results in the standard deviation remaining the same.
Multiplying each data value by the same constant c results in the standard deviation increasing by c units.
Multiplying each data value by the same constant c results in the standard deviation being |c| times smaller.
O Multiplying each data value by the same constant c results in the standard deviation being |c| times as large.
(d) You recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.4 miles. Your friend
wants to know the standard deviation in kilometers. Do you need to redo all the calculations?
Yes
No
Given 1 mile z 1.6 kilometers, what is the standard deviation in kilometers? (Enter your answer to two decimal places.)
S =
km
