Question

Human body temperatures are normally distributed with a mean of 98.20°F and a standard deviation of 0.62°F. Find the temperature that separates the top 7% from the bottom 93%. Round to the nearest hundredth of a degree.

Answer 1

z = 1.476 = (x-98.2)/.62

x=98.2+.62(1.476= 99.115 = about 99.12 degrees is the temperature that separates top 7% from bottom 93%

99.115-98.2= .915

98.2-.915= 97.485 separates bottom 7 from top 93
