Use the Central Limit Theorem to find the mean and standard error of the mean of the indicated sampling distribution. The amounts of time employees of a telecommunications company have worked for the company are normally distributed with a mean of 5.80 years and a standard deviation of 1.80 years. Random samples of size 14 are drawn from the population and the mean of each sample is determined. Round the answers to the nearest hundredth. O A. 1.55 years, 1.80 years O B. 1.55 years, 0.48 years OC. 5.80 years, 0.13 years O D. 5.80 years, 0.48 years
