Assume the body temperatures of healthy adults are normally, Ask an Expert

Statistics

Assume the body temperatures of healthy adults are normally distributed with a mean of 98.20°F and a standard deviation of 0.62°F (based on data from the University of Maryland researchers).

Fifty adults are randomly selected. What is the likelihood that the mean of their body temperatures is 97.98°F or lower?

A person's body temperature is found to be 101.00°F. Is the result unusual? Why or why not? What should you conclude?

Bellevue Hospital in New York City uses 100.6°F as the lowest temperature considered to indicate a fever. What percentage of normal and healthy adults would be considered to have a fever?
