When asked: "What is the distribution of X ? X ~ N(___,___)." This notation is referring toN, a normal distribution, with the mean given in the first space and the standard deviationin the second space. Remember that the standard deviation of the sample means isdifferent from the population standard deviation.The lengths of adult males' hands are normally distributed with mean 190 mm andstandard deviation 7 mm. Suppose that 11 individuals are randomly chosen. Round finalanswers to 4 decimal places.a. What is the distribution of x? x N(b. For the group of 11, find the probability that the average hand length is more than189.c. 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? YesNo

here given for population mean = 190 mm standard deviation = 7 mm

Answered: a. What is the distribution of ? - NO…
