To test the effect of alcohol in increasing the reaction time to respond to a given stimulus, the reaction times of seven people were measured both before and after consuming 3 ounces of 40% alcohol. Do the following data indicate that the mean reaction time after consuming alcohol was greater than the mean reaction time before consuming alcohol? Use a = 0.05. (Use before Hafter =) Person 2 1 Before 3 4 After 8 7 USE SALT 3 6 2 4 5 6 5 4 5 6 7 7 1 6 6 State the null and alternative hypotheses.

To test the effect of alcohol in increasing the reaction time to respond to a given stimulus, the reaction times of seven people were measured both before and after consuming 3 ounces of 40% alcohol. Do the following data indicate that the mean reaction time after consuming alcohol was greater than the mean reaction time before consuming alcohol? Use α = 0.05. (Use μ_before = μd = μ_after). **Data Table:** | Person | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |--------|---|---|---|---|---|---|---| | Before | 3 | 4 | 6 | 5 | 5 | 4 | 1 | | After | 8 | 7 | 2 | 6 | 5 | 9 | 4 | **Hypotheses Options:** 1. H₀: μd ≠ 0 versus H₃: μd = 0 2. H₀: μd = 0 versus H₄: μd ≠ 0 3. H₀: μd = 0 versus H₅: μd < 0 4. H₀: μd < 0 versus H₅: μd > 0 5. H₀: μd = 0 versus H₆: μd > 0 **Tasks:** - State the test statistic (t value). - State the rejection region. For unused region, write NONE. Answers should be to three decimal places. - Conclude based on the hypothesis: - H₀ is not rejected: There is sufficient evidence that the mean reaction time is greater after consuming alcohol. - H₀ is not rejected: There is insufficient evidence that the mean reaction time is greater after consuming alcohol. - H₀ is rejected: There is insufficient evidence that the mean reaction time is greater after consuming alcohol. - H₀ is rejected: There is sufficient evidence that the mean reaction time is greater after consuming alcohol.
