Suppose that human body temperature are normally distributed with a mean of 98.2 degrees F and a standard deviation of 0.62 degrees F.

1. Physicians want to select the lowest body temperature considered to be a fever and decide that only 5% of the population should exceed the temperature. What values should they use for this temperature?

2. Suppose that one individual is selected at random. Find the probability that their temperature will exceed 100 degrees F.

3. Suppose that 4 individuals are selected at random. Find the probability that the sample mean will exceed 98.7 degrees F

Assume that the population of human body temperatures has a mean of 98.6 degrees F, as is commonly believed. Also assume that the population has a standard deviation of 0.62 degrees F. If a sample size of n=106 is randomly selected, find the probability of getting a mean of 98.2 degrees F or lower. (Verify that the central limit theorem applies if you are using it.) A study was done with this sample size of 106 randomly selected adults and...

Healthy people have body temperatures that are normally distributed with a mean of 98.20∘F and a standard deviation of 0.62∘F (a) If a healthy person is randomly selected, what is the probability that he or she has a temperature above 98.7∘F? answer: (b) A hospital wants to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 1.5 % of healthy people to exceed it? answer: NormalDistribution

Average temperature of a dog is 37°C, or 98.6°F. A Researcher reported that it was 98.2°F, with a standard deviation of 0.7°F. Assume that the body temperatures in degrees F are normally distributed. If the researchers’ statistics for the mean and standard deviation are correct: i) Calculate the probability the average body temperature of these four dogs is less than 98.5°F. Suppose that a vet nurse takes the body temperature of 10 dogs, none with illness or disease that will...
