Safe cities. Exercise IV.1 concerns a random sample of 1001 adults.

Suppose that (unknown to the pollsters) exactly 85% of all adults would rate Seattle as safe to live in or visit. Imagine that we take very many SRSs of size 1001 from this population and record the percentage in each sample who choose Seattle as safe. Where would the middle 95% of all values of this percentage lie? (Hint: See pages 457–461.)
