The lengths of adult males' hands are normally distributed with mean 188 mm and standard deviation is 7.3 mm. Suppose that 7 individuals are randomly chosen. Round all answers to 4 where possible. What is the distribution of ¯xx¯? ¯xx¯ ~ N(,) For the group of 7, find the probability that the average hand length is less than 191. Find the first quartile for the average adult male hand length for this sample size.
