You select a random sample of n = 14 families in your neighborhood and find the following family sizes (number of people in the family).
15, 16, 16, 15, 19, 16, 18, 15, 17,16, 15,17,16, 18
I found the mean family size which is 16.4. I found the mean family size by adding all of the numbers above and dividing by 14.
b. What is the standard deviation for the sample? (Round to the nearest tenth)
