Below are a number of situations associated with vacations. For each, first determine and select if the appropriate method to address the problem would be to make a confidence interval (CI) or to conduct a test of hypotheses (HT). Next, select the appropriate notation for the corresponding parameter(s). As a challenge for yourself: think about what would be the appropriate corresponding formula for creating the interval estimate (if CI) or for computing the test statistic (if HT).

Your friend is trying to decide where they want to go on vacation. They are considering two destinations: Cancun, Mexico and Miami, Florida. Your friend believes that going to an all-inclusive resort will result in a less expensive trip, so they would like to estimate which of the two locations has a higher rate of all-inclusive resorts among the hotel accommodations in the area.

A. Make a confidence interval (CI)
B. P1-P2
