Human Body Temperatures Taken Through the Ear Are Typically 0

Essay

Human body temperatures taken through the ear are typically 0.5° F higher than body temperatures taken orally. Making this adjustment and using the 1992 Journal of the American Medical Association article that reports average oral body temperature as 98.2° F, we will assume that a Normal model with an average of 98.7° F and a standard deviation of 0.7° F is appropriate for body temperatures taken through the ear.
a. An ear temperature of 97° F may indicate hypothermia (low body temperature). What
percent of people have ear temperatures that may indicate hypothermia?
b. Find the interquartile range for ear temperatures.
c. A new thermometer for the ear reports that it is more accurate than the ear thermometers
currently on the market. If the average ear temperature reading remains the same and the
company reports an IQR of 0.5° F, find the standard deviation for this new ear thermometer.
