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. Current Year Previous Year Occupied Rooms 1,435 1,422 Total Rooms 1,750 1,800 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. Let p1 2 population proportion of rooms occupied for current year 102 2 population proportion of rooms occupied for previous year H0 : p1 p2 - Select your answer - v Ha : P1 P2 - Select your answer - v b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? Current year Previous Year c. Conduct a hypothesis test. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. pvalue = Using a 0.05 level of signicance, what is your conclusion? We that there has been an increase in the hotel occupancy rate. d. What is the 95% confidence interval estimate of the change in occupancy for the one-year period (to 4 decimals)? to Do you think area officials would be pleased with the results? Ofcials would likely be with the occupancy statistics as the trend for the current year is in hotel occupancy rates compared to last year. TABLE 1 Cumulative Probabilities for the Standard Normal Distribution Entries in the table give the area under the Cumulative curve to the left of the probability z value. For example, for z = -.85, the cumulative probability is . 1977. 0 Z .00 01 .02 .03 .04 .05 .06 07 08 .09 -3.0 .0013 0013 .0013 .0012 0012 001 1 .0011 .0011 .0010 0010 -2.9 0019 0018 .0018 0017 . 0016 0016 0015 0015 .0014 .0014 -2.8 .0026 .0025 .0024 .0023 .0023 0022 .0021 .0021 .0020 .0019 -2.7 .0035 0034 .0033 .0032 0031 0030 .0029 .0028 .0027 .0026 -2.6 .0047 .0045 .0044 .0043 .0041 0040 .0039 .0038 .0037 .0036 -2.5 .0062 .0060 .0059 .0057 .0055 0054 .0052 .0051 .0049 .0048 -2.4 0082 .0080 .0078 0075 .0073 0071 .0069 .0068 0066 0064 -2.3 .0107 0104 .0102 .0099 .0096 0094 .0091 .0089 .0087 .0084 -2.2 0139 0136 0132 0129 .0125 0122 0119 . 01 16 0113 .0110 -2.1 .0179 0174 .0170 .0166 .0162 0158 .0154 .0150 0146 .0143 -2.0 .0228 .0222 .0217 .0212 .0207 .0202 .0197 .0192 .0188 .0183 -1.9 0287 .0281 .0274 0268 .0262 .0256 .0250 .0244 0239 .0233 -1.8 .0359 0351 .0344 .0336 .0329 0322 0314 .0307 0301 .0294 -1.7 .0446 .0436 .0427 .0418 0409 0401 .0392 .0384 .0375 .0367 -1.6 0548 .0537 .0526 0516 .0505 .0495 .0485 .0475 0465 .0455 -1.5 0668 0655 .0643 0630 .0618 0606 .0594 .0582 .0571 .0559 -1.4 .0808 .0793 .0778 .0764 .0749 .0735 .0721 .0708 .0694 .0681 -1.3 .0968 0951 .0934 . 0918 .0901 .0885 0869 .0853 0838 .0823 -1.2 . 1 151 1131 .1112 1093 . 1075 .1056 . 1038 .1020 .1003 .0985 -1.1 .1357 .1335 .1314 . 1292 .1271 . 1251 .1230 . 1210 . 1190 .1170 -1.0 1587 .1562 . 1539 . 1515 .1492 .1469 . 1446 .1423 1401 .1379 -.9 1841 . 1814 .1788 .1762 . 1736 1711 .1685 .1660 .1635 . 1611 -.8 .2119 .2090 .2061 .2033 .2005 1977 .1949 . 1922 . 1894 .1867 -7 .2420 .2389 .2358 2327 .2296 2266 .2236 .2206 2177 .2148 -.6 .2743 .2709 .2676 .2643 .2611 .2578 .2546 .2514 .2483 .2451 -5 3085 .3050 .3015 .2981 .2946 .2912 .2877 .2843 .2810 .2776 -.4 .3446 .3409 .3372 3336 .3300 3264 3228 .3192 .3156 3121 -.3 3821 .3783 .3745 .3707 .3669 .3632 .3594 .3557 .3520 .3483 -.2 4207 .4168 .4129 4090 .4052 4013 .3974 .3936 .3897 .3859 -.1 4602 .4562 .4522 .4483 .4443 4404 .4364 4325 .4286 .4247 .0 .5000 .4960 .4920 .4880 .4840 .4801 .4761 .4721 .4681 .4641
