A random sample of 10 students were surveyed on their social activities. The students were asked to state how many times during the previous year they had gone to a movie, sporting event, or party. The accompanying technology output shows the result of comparing the mean responses on parties and sports. U this output to complete parts a through d below. i Click the icon to view the technology output of comparing the mean responses on parties and sports. a. Explain how to interpret the reported 99% confidence interval. It can be stated with 99% confidence that the population mean difference is between | and . Because 0 in this interval, there to be a difference between attendance at parties and sporting events. (Round to two decimal places as needed.) b. State the hypotheses to which the P-value refers and interpret its value. Complete the hypotheses below. Ho: Students attend number of parties and sporting events, or Hd o. Ha: Students attend number of parties and sporting events, or Ha o Interpret the P-value using a significance level of 0.01. If the null hypothesis is the probability of getting a test statistic as the observed value is . This sufficient evidence to reject the null hypothesis. (Round to three decimal places as needed.) c. Explain the connection between the results of the test and the confidence interval. Choose the correct answer below. O A. When the confidence interval contains 0, the null hypothesis cannot be rejected at a corresponding significance level, and vice versa. Similarly, when the confidence interval does not contain 0, the null hypothesis can be rejected at a corresponding significance level. O B. Since the hypothesis test is more robust than the confidence interval, it is possible for the confidence interval to not contain 0, but not be able to reject the null hypothesis at a corresponding significance level. However, if the null hypothesis can be rejected, then the confidence interval will not contain 0. O C. The confidence interval and hypothesis test rely on different assumptions. While they will often result in the same conclusion, small sample sizes or departures from normality may cause their conclusions to differ O D. Since the confidence interval is more robust than the hypothesis test, it is possible for the confidence interval to contain 0 and to reject the null hypothesis at a corresponding significance level. However, if the confidence interval does not contain 0, then the null hypothesis will not be rejected. d. What assumptions are necessary for these inferences to be appropriate? Select all necessary assumptions and/or conditions below. A. The sample of difference scores is a random sample from a population of difference scores. B. Every student attends both parties and sporting events. C. The sample size is at least 30. i Technology Output - X OD. Each population is normally distributed. E. The difference scores have a population distribution that is approximately normal.
