Step 1
This is done by adding the lower and upper limit of each range and dividing by 2. For 50-59, the midpoint is 54.5 For 60-69, the midpoint is 64.5 For 70-79, the midpoint is 74.5 For 80-89, the midpoint is 84.5 For 90-99, the midpoint is 94.5 For 100-109, the Show more…

Human body temperatures for healthy individuals have approximately a normal distribution with mean $98.25^{\circ} \mathrm{F}$ and standard deviation. $75^{\circ} \mathrm{F} .$ The past accepted value of $98.6^{\circ} \mathrm{F}$ was obtained by converting the Celsius value of $37^{\circ},$ which is correct to the nearest integer.) (a) Find the 90th percentile of the distribution. (b) Find the 5 th percentile of the distribution. (c) What temperature separates the coolest 25$\%$ from the others?
