Chapter 6: Normal Probability Distributions

Ex #4: Assume that the population of human body temperatures has a mean of 98.6ºF (as is commonly believed). Also assume that the population standard deviation is 0.62ºF (based on data from University of Maryland researchers). If a sample size n = 106 is randomly selected, find the probability of getting a mean of 98.2ºF or lower. ................
