The body temperatures of a group of healthy adults have a​bell-shaped distribution with a mean of
98.2198.21degrees°F
and a standard deviation of
0.540.54degrees°F.
Using the empirical​ rule, find each approximate percentagebelow.
a. | What is the approximate percentage of healthy adults with bodytemperatures within 11 standarddeviationdeviation of the​ mean, or between97.6797.67degrees°F and98.7598.75degrees°​F? |
b. | What is the approximate percentage of healthy adults with bodytemperatures between 97.1397.13degrees°F and99.2999.29degrees°​F? |
