Heights of Women In a survey of U.S. women, The heights in the 20- to 29-year age group were normally distributed, with a mean of 64.2 inches and a standard deviation of 2.9 inches. Find the probability that a randomly selected study participant has a height that is more than 56.5 inches The pregnancy length (in days) for a population of new mothers can be approximated by a normal distribution, with a mean of 267 days and a standard deviation of 10 days. What is the minimum pregnancy length that can be in the top 8% of pregnancy lengths? The weights of ice cream cartons are normally distributed with a mean weight of 10 ounces and a standard deviation of 0.5 ounce. You randomly select 4 cartons. What is the probability that their mean weight is greater than 10.40 ounces?
