Q Search this omework 6 (Chapter 10) - Part A O 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 Occupled Rooms 1,476 1,404 Total Rooms 1,800 1,800 a. Formulate the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupled over the one-year period. Let pi = population proportion of rooms occupied for current year Pa = population proportion of rooms occupled for previous year Ho : P1 - Pa - Select your answer H: P - Pa Select your answer 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-vålue (to 4 decimals)?

Section 5.4 (Please help with TI-84 calculator) thank you The average math SAT score is 521 with a standard deviation of 118. A particular high school claims that its students have unusually high math SAT scores. A random sample of 60 students from this school was selected, and the mean math SAT score was 565. Is the high school justified in its claim? Explain No or Yes, because the z-score is (_________) is unusual or usual since it does not lie or lies within the range of a usual event, namely within ( 1standard deviation, 2 standard deviation, or 3 standard deviation) of the mean of the sample means.
