1. (4pts) Suppose that in a population of home owners, in a certain region, 38% are in favor of particular new neigborhood zoning policy. Nine hundred randomly selected house owners are asked if they favor the new neigborhood zoning policy. (a) What is the approximate distribution of p? (b) What is the approximate probability that the proportion estimate falls between 5 per- centage points of the true population proportion? (c) What is the exact probability that the proportion estimate falls between 5 percentage points of the true population? (You can use R as a calculator.) Hint: What is an equivalent event to a < ô < b in terms of X where p = X.? (d) How large is the error between the approximation and the true probability?
