Question Which
of the data sets represented by the following histograms has the smallest
standard deviation?

A histogram
has a horizontal axis from 0 to 140 in increments of 20 and a vertical axis
from 0 to 140 in increments of 20. The histogram has vertical bars of width 3,
starting at the horizontal axis value of 58. The approximate heights of the
bars are as follows, where the horizontal axis label is listed first and the
approximate height is listed second: 58, 1; 61, 10; 64, 36; 67, 78; 70, 150;
73, 150; 76, 138; 79, 72; 82, 22; 85, 5.

A histogram has a horizontal axis from 0 to
140 in increments of 20 and a vertical axis from 0 to 140 in increments of 20.
The histogram has vertical bars of width 3, starting at the horizontal axis
value of 43. The approximate heights of the bars are as follows, where the
horizontal axis label is listed first and the approximate height is listed
