At Center Hospital there is some concern about the high turnover of nurses. A survey was done to determine how long (in months) nurses had been in their current positions. The responses (in months) of 20 nurses were as follows.

5, 8, 10, 11, 11, 14, 15, 17, 23, 26, 26, 28, 29, 30, 31, 32, 34, 39, 39, 45

A) Calculate the mean and standard deviation of this sample. (Round mean value to 2 decimal places and standard deviation to 3 decimal places)
