According to a study, the length of pregnancy has an unknown distribution with a mean of 265 days and a standard deviation of 15.4 days. Let XX be the length of pregnancy for a randomly selected female and let ¯¯¯XX¯  be the average length of pregnancy for a random sample of size 22. 1. Describe the probability distribution of XX and state its parameters μμ and σσ:  X∼X∼         ( μ=μ= , σ=σ= ) 2. Explain why the Central Limit Theorem can or can not be applied The Central Limit Theorem for Sample Means     be applied because
