Question: Consumption of a large amount of alcohol is known to increase reaction time. To investigate the effects of small amounts of alcohol, reaction time was recorded for five individuals before and after 2 ounces of alcohol was consumed by each. Does the data below suggest that the consumption of 2 ounces of alcohol increases mean reaction time?

Reaction Time (seconds)
Subject Before After
1 6 7
2 8 8
3 4 6
4 7 10
5 9 10

Assume we want to use a 0.10 significance level to test the claim.

  1. Identify the null hypothesis and the alternative hypothesis.
  2. Determine the test statistic. Show all work; writing the correct test statistic, without supporting work, will receive no credit.
  3. Determine the p-value. Show all work; writing the correct critical value, without supporting work, will receive no credit.
  4. Is there sufficient evidence to support the claim that the consumption of 2 ounces alcohol increases mean reaction time? Justify your conclusion.
