The amounts of time employees of a telecommunications company have worked for the company are normally distributed with a mean of 5.7 years and a standard deviation of 2.1 years. Random samples of size 15 are drawn from the population and the mean of each sample is determined.
Use the Central Limit Theorem to find the mean and standard
error of the mean of the indicated sampling distribution.
