Question

I randomly selected a small size sample of seven players and asked them their age. The results are listed below. From this sample, determine the mean age of these seven players. (4) Now determine the standard deviation of these ages. (4) So, what was the average age of all the players in the Rouge Hill Masters' Basketball League?(2)
