3) Human body temperatures are normally distributed with a mean of 98.20°F and a standard deviation of 0.62°F. If 19 people are randomly selected, find the probability that their mean body temperature will be less than 98.50°F
Added by Tanner M.
Step 1
- Population mean, \( \mu = 98.20^\circ F \) - Population standard deviation, \( \sigma = 0.62^\circ F \) - Sample size, \( n = 19 \) - We want to find \( P(\bar{X} < 98.50) \), where \( \bar{X} \) is the sample mean. Show more…

Human body temperatures are normally distributed with a mean of 98.20°F and a standard deviation of 0.62°F. a. If 1 person is randomly selected, find the probability that he/her has body temperature less than 99.65°F. b. If 60 people are randomly selected, find the probability that their mean body temperature will be less than 99.65°F. c. Explain what is the difference in the questions and why is there a difference in the answers.
