- Check My Work (4 remaining) 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 1,505 1,411 Total Rooms 1,750 1,700 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 pi = population proportion of rooms occupied for current year p2 = population proportion of rooms occupied for previous year Ho : Pi – P2 equal to 0 H. : Pi – P2 equal to 0 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. p-value = Using a 0.05 level of significance, what is your conclusion? We - Select your answer -…Answer these questions A, B, C and D questionHypothesis testing will consist of four hypothesis tests which you need to complete. each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:
- Test the claim that the proportion of people who own cats is significantly different than 80% at the 0.1 significance level. The alternative hypothesis would be: p 0.8 u > 0.8 µ < 0.8 p # 0.8 µ # 0.8 o The test is: left-tailed two-tailed right-tailed Based on a sample of 500 people, 75% owned cats The test statistic is: (to 2 decimals) The p-value is: (to 2 decimals)The following table contains the number of successes and failures for three categories of a variable. Test whether the proportions are equal for each category at the a 0.1 level of significance. Category 1 Category 2 Category 3 Failures 84 34 48 Successes 65 72 62 State the hypotheses Choose the correct answer below. A H The categories of the variable and success and failure are dependent. H, The categories of the variable and success and failure are independent. B H PP2"P3 H, At least one of the proportions is different from the others. He The categories of the variable and success and failure are independent. H, The categories of the variable and success and failure are dependent. D. Ho H=E, and u, =E, and ua =E H, At least one mean is different from what is expected What is the P-value? (Round to three decimal places as needed.)Answer all these questions. A, B and C questions
- Which of the following is the name for the statistical hypothesis that describes an outcome of some change? Type I error Null hypothesis Alternative hypothesis Type II errorIn hypothesis testing, if the test statistic is negative, this means the sample statistic is larger than the claimed population parameter. O we call the initial claim being tested about the population an alternative hypothesis. the "P" in P-value stands for "personal." O it is necessary to know the population size in order to compute the test statistic. O results that are statistically significant may or may not be practically important (or practically significant).Scenario: Erna Economist claims that a majority of Americans feel that corporations make too much profit. According to a 2019 Pew Research poll, 56% of a random sample of 1,500 adults said that business corporations make too much profit. Run a hypothesis test to assess Erna Economist's claim.
