Question
Need help solving first three parts
**Study on the Effect of Alcohol on Reaction Time** 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. The question is: Do the following data indicate that the mean reaction time after consuming alcohol is greater than the mean reaction time before consuming alcohol? Use \( \alpha = 0.05 \). (Use \( \mu_{\text{before}} - \mu_{\text{after}} = \mu_d \).) | Person | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |---------|---|---|---|---|---|---|---| | Before | 5 | 8 | 6 | 7 | 5 | 5 | 3 | | After | 6 | 9 | 2 | 6 | 3 | 4 | 4 | **State the Null and Alternative Hypotheses:** - \( H_0: \mu_d = 0 \) versus \( H_a: \mu_d > 0 \) - \( H_0: \mu_d = 0 \) versus \( H_a: \mu_d < 0 \) - \( H_0: \mu_d < 0 \) versus \( H_a: \mu_d > 0 \) - \( H_0: \mu_d \neq 0 \) versus \( H_a: \mu_d = 0 \) - \( H_0: \mu_d = 0 \) versus \( H_a: \mu_d \neq 0 \) **Test Statistic:** State the test statistic. (Round your answer to three decimal places.) \( t = \_\_\_ \) **Critical Value Approach:** Use the critical value approach to state the rejection region. (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.) \( t > \_\_\_ \) \( t < \_\_\_ \) **Conclusion:** - \( H_0 \) is not rejected. There is sufficient evidence to indicate that the mean reaction time is greater after consuming alcohol. - \( H_0 \) is rejected. There is insufficient evidence to indicate that the mean reaction time is greater after consuming alcohol
