1. The ages (in years) of the 6 doctors at a local clinic are 35, 45, 42, 43, 32, 43. Assuming that these ages constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places.
2. The tourist bureau of the Hawaiian Islands surveyed a sample of United States tourists as they left to return home. The tourists were asked how many days they spent on their visits. Their responses were as follows : 4, 8, 6, 11, 6
Find the standard deviation of this sample of numbers. Round your answer to at least two decimal places
Please help I do not understand these two problems?
Refer to this page:

It talks about exactly what you are looking for about 1/2 down the page.
Good luck.
