The amounts of time employees at a large corporation work each day are normally​ distributed, with a mean of 7.8 hours and a standard deviation of 0.36 hour. Random samples of size 25 and 37 are drawn from the population and the mean of each sample is determined. What happens to the mean and the standard deviation of the distribution of sample means as the size of the sample​ increases? If the sample size is nequals25​, find the mean and standard deviation of the distribution of sample means.
