The State of Colorado suspects that tourism has increased this year (as compared with last year). In order to test if this was actually the case, the secretary of tourisms decides to analyze hotel occupation last year vs. this year. There are too many hotels in Colorado which makes practically impossible to gather data from all hotels. Occupation data from a sample of 1750 rooms is collected and compared with another sample of 1800 rooms collected last year. The data is as follows. Current Previous Year Year Occupied Rooms 1470 1458 Total Rooms 1750 1800

Current Previous Year Year Occupied Rooms 1470 1458 Total Rooms 1750 1800 Part a: Formulate the hypothesis test that can be used to determine if there has been an increase in the proportion of rooms occupied over the one-year period. • Null Hypothesis (Ho): [ Select] • Alternative Hypothesis: [ Select] Part b. Calculate the Z statistic and the p-value • The z statistic is = [ Select] • The p-value is = [ Select] Part c. Using a .05 level of significance, what is your hypothesis test conclusion? [ Select ]
