Winter visitors are extremely important to the economy of Southwest Florida. Hoteloccupancy is an often-reported measure of visitor volume and visitor activity (naplesdaily news, March 22, 2012). Hotel occupancy data for February in two consecutiveyears are as follows.OccupancyCurrent Year Previous YearOccupied Rooms 1470 1458Total Rooms 1750 1800a. Formulate the hypothesis test that can be used to determine if there has been anincrease in the proportion of rooms occupied over the one-year period.b. What is the estimated proportion of hotel rooms occupied each year?c. Using a .05 level of significance, what is your hypothesis test conclusion? What is thep-value?d. What is the 95% confidence interval estimate of the change in occupancy for the oneyear period? Do you think area officials would be pleased with the results?
You come across Professor Cafferty's data set from his Master's thesis and realize that he has data on types of family support that 26 homosexual men had during young adulthood (about 18-25 years old). You come across two questions where the respondent was asked if they would identify their family as religious and whether or not they received financial support from their family. Please complete the appropriate 8-step hypothesis test using the data below.

A sample of consumers 21 years and older in Milwaukee will be taken, and the sample mean 2017 beer and cider consumption will be used to test the following null and alternative hypotheses: H0 : μ ≤ 26.9Ha: μ > 26.9a.
