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 = ud) 1 2 3 4 5 6 7 Person Before After 3 6 3 2 7 3 4 9 8 4 6 3 4 6 in USE SALT State the null and alternative hypotheses. O Ho: Mo - 0 versus H: Mo<0 O Hoi Hd = 0 versus Hai Hd > 0 O Ho: Mo O versus Hy: Mg> 0 O Hoi Hd = 0 versus Ha: 487 0 O Ho: Mo # O versus H : Hg = 0 State the test statistic. (Round your answer to three decimal places.) State the rejection region. (If the test is one-ta NONE for the unused region. Round your answer to three dec places.) State the conclusion. OH, is rejected. There is insufficient evidence to indicate that the mean reaction time is greater after consuming alcohol. O Ho is rejected. There is sufficient evidence to indicate that the mean reaction time is greater after consuming alcohol. O Ho is not rejected. There is sufficient evidence to indicate that the mean reaction time is greater after consuming alcohol. O Ho is not rejected. There is insufficient evidence to indicate that the mean reaction time is greater after consuming alcohol.
