- Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018). Hotel occupancy data for February in two consecutive years are as follows. Occupied Rooms Total Rooms Current Year Let pi population proportion of rooms occupied for current year P = population proportion of rooms occupied for previous year 1,435 1,750 Previous Year a. Formulate the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupied over the one-year period. Ho Pi-Pa-Select your answer- H.: P-P-Select your answer- b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? 1,404 1,800 Current year Previous Year c.
