The body temp of normal healthy persons are normally distributed with a mean of 98.2 degrees F and a standard deviation od .62 degree F. If we define a fever to be a body temp above 100 degrees F, what percentage of normal and healthy person would be considered to have a fever?

μ=98.2
σ=0.62
Z(100)=(10098.2)/0.62=2.903
Look up (normal) probabilities for Z=2.903 from tables (for people with temperatures below 100).
Subtract from 1 to get probabilities of healthy person considered having a fever. 
ATTENDANCE14If the mean body temperature is not known, however it is known that 10% of all people have body temperatures greater than 99.5 degrees Fahrenheit, what would the mean body temperature be? Assume the standard deviation is 0.5 degrees and body temperature is normally distribute
