Reaction time ~ For a special back-to-school event, the student council at a small liberal arts college invited a panel of 7 recent graduates to help demonstrate to students the adverse effect of alcohol on reaction time. The reaction times (in seconds) before and after consuming four alcoholic drinks are shown in the table. Participant Difference = After - Before 0.36 0.42 0.06 0.42 0.51 0.09 Round all calculated values to 4 decimal places as appropriate. 1. Which set of hypotheses should we use to conduct a paired difference test to determine if drinking increases reaction time? OA. H0 2 ludiff : OVS. Ha :Hdiff 0 OD. H0 1 ludiff 009 2. What conditions must be met if we want to perform this hypothesis test? Select all that apply: DA. There must be an expected count of at least 5 for each participant in the study. C] B. Independently sampled pairs. Damp Z 10 and n(1 p) Z 10 C] D. Large samples and no extreme outliers. 3. Assuming the conditions for the hypothesis test are met, find the test statistic and the p-value. test statistic = p-value = 4. Based on the p value we have ? v evidence that the null model is not a good fit for our observed data. 5. Construct a 99% confidence interval for the average change in reaction time
