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 9,6,8,14, 17. A) use the defining formula, the computation formula. B) multiply each data value by 5 to obtain the new data set 45, 30, 40, 70 85. Compute s

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

this answer is !
