The lengths of adult males' hands are normally distributed with mean 193 mm and standard deviation is 7.2 mm. Suppose that 16 individuals are randomly chosen. Round all answers to 4 decimal places where possible. a. What is the distribution of 2 - N( L ) b. For the group of 16, find the probability that the average hand length is less than 192. . Find the first quartile for the average adult male hand length for this sample size. d. For part b), is the assumption that the distribution is normal necessary? ) No( Yes
