3.32 What Percent of the US Population Are Senior Citizens? People 65 years and older are the fastest growing segment of the US population, and constituted 13% of the population in 2010.19 Figure 3.10 shows sample proportions from two sampling distributions of the proportion 65 years and older in the US: One shows samples of size 100, and the other shows samples of size 1000. (a) What is the center of both distributions? (b) What is the approximate minimum and maxi- mum of each distribution? (c) Give a rough estimate of the standard error in each case.
