You select a random sample of n=14 families in your neighborhood and find the following family sizes (number of people in the family) 1,2,5,4,3,1,2,2,1,2,12,3,4 a. What is the best estimate for the mean family size for the population of all families in a country? (round to the nearest tenth as needed) b. What is the 95% confidence interval for the estimate? __
