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.

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. After consuming89 mLof40% alcohol,the reaction time for each of the seven people was measured again. Do the following data indicate that the mean reaction time after consuming alcohol was greater than the mean reaction time before consuming alcohol? Use = 0.05.(Use

before after = d.

Round your answers to three decimal places.)

Person 1 2 3 4 5 6 7
Before 4 5 6 3 4 5 1
After 8 7 4 5 4 5 5

1-2. Null and alternative hypotheses: H0: d 0 versus d = 0H0: d < 0 versus d > 0 H0: d = 0 versus d < 0H0: d = 0 versus d 0H0: d = 0 versus d > 0 3. Test statistic: t= 4. Rejection region: If the test is one-tailed, enter NONE for the unused region.

t >
t <

5. Conclusion: H0 is rejected. There is insufficient evidence to indicate that the mean reaction time is greater after consuming alcohol.H0 is rejected. There is sufficient evidence to indicate that the mean reaction time is greater after consuming alcohol. H0 is not rejected. There is insufficient evidence to indicate that the mean reaction time is greater after consuming alcohol.H0 is not rejected. There is sufficient evidence to indicate that the mean reaction time is greater after consuming alcohol.
