1. A normal population has a mean of 73 and standard deviation of 14. You select randomsamples of nine.(a) Describe the sampling distribution of the sample mean with n = 9, i.e. specify theexpected value of sample means of size 9, the standard error, and the shape of thedistribution (if the shape is normal, explain why).(b) What is the probability that a sample mean is between 69 and 76?
