a) Null and alternative hypothesis b) Appropriate test to use c) Tail of the distribution d) Decision Rule 1. A study was conducted to investigate the effectiveness of hypnotism in reducing pain. Results for randomly selected subjects are given in the accompanying table (based on "An analysis of Factors that contribute to the efficacy of Hypnotic Analegsia"). The values are before and after hypnosis; the measurements are in centimeters on a pain scale. Use a 5% level of significance to test the claim that hypnotism is effective in reducing pain.

A researcher is interested in the effect type of residence has on the personal happiness of college students. She selects samples of students who live in campus dorms, in off-campus apartments, and at home and asks the respondents to rate their happiness on a scale of 1 (not happy) to 10 (happy). Her data are reported below A) Write research and null hypotheses B) Does happiness differ by type of residence? Test with an α = 0.01.C) What type of error is possible based on the outcome?D) On average, which residence type has the highest amount of personal happiness? Report the mean.E) On average, which residence type has the lowest amount of personal happiness? Report the mean. F) If appropriate, use Scheffe’s post hoc test and report where the differences are. If inappropriate, state why.G) Calculate and interpret the effect size

A manufacturer claims that 10% of women using the "pill" suffer from side effects. The Federal Drug Administration (FDA) believes that the manufacturer's claim is too low and decides to test the manufacturer's claim at a = 5 %. A random sample of 900 women who use the manufacturer's pill shows that 103 suffer side effects. %3D The test statistic is: a. 2.33 Ob. 1.59 C. 1.65 Od. 1.44 Oe.

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. Let P1= population proportion of rooms occupied for current year P2= population proportion of rooms occupied for previous year 1,476 1,800 1,343 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. Current year Ho: P1-P2 - Select your answer - Ha P1 P2 - Select your answer - b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? Previous Year Occupied Rooms Total Rooms * 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? Current Year to Do you think area officials would be pleased…
