To test the effect of alcohol on 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 = μ_d) Table of Reaction Times: | Person | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |--------|---|---|---|---|---|---|---| | Before | 5 | 4 | 6 | 3 | 2 | 7 | 3 | | After | 8 | 9 | 9 | 6 | 5 | 6 | 6 | ### Instructions: **State the null and alternative hypotheses:** - \( H_0 \): μ_d = 0 versus \( H_1 \): μ_d > 0 - \( H_0 \): μ_d = 0 versus \( H_1 \): μ_d ≠ 0 - \( H_0 \): μ_d = 0 versus \( H_1 \): μ_d = 0 - \( H_0 \): μ_d = 0 versus \( H_1 \): μ_d < 0 **State the test statistic. (Round your answer to three decimal places.)** t = _______ **State the rejection region. (If the test is one-tailed, enter NONE for the unused region.
