Hotel occupancy data for February in two consecutive years are as follows. Current Year Previous Year Occupied Rooms 1,584 1,445 Total Rooms 1,800 1,700 a. Formulate the hypothesis test that can be used to determine whether thenre has been an increase in the proportion of rooms occupied over the one-year period. Let p = population proportion of rooms occupied for current year P = population praportion of rooms occupied for previous year Ho : Pi - Pa less than or equal to o H: - P greater than o b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? Current year .88 Previous Year .85 c. Conduct a hypothesis test. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. p-value - .0047 Using a 0.05 level of significance, what is your conclusion? We can condude v that there has been an increase in the hotel occupancy rate. d.
