Question:
We see in the All-Countries dataset that the percent of the population that is elderly (over 65 years old) is 17.0 in Austria and 15.9 in Denmark. Suppose we take random samples of size 200 from each of these countries and compute the difference in sample proportions p̂A − p̂D, where p̂A represents the proportion of the sample that is elderly in Austria and p̂D represents the proportion of the sample that is elderly in Denmark. Find the mean and standard deviation of the differences in sample proportions.
