A recent news article reported that the mean amount of leisure time per week for European men is 40 hours. You believe this figure is too large and decide to conduct your own test. In a random sample of 25 men, you find that the mean is 37.8 hours of leisure per week and that the standard deviation of the sample is 12.2 hours. Can you conclude that the information in the article is untrue? Test at the 0.05 level of significance. Use this data for questions 7 to 12.

Choose the correct null and alternative hypotheses.

Since the test statistic falls in the non-rejection region, we reject the null hypothesis.

Since the test statistic does not fall in the non-rejection region, we fail to reject the null hypothesis.

Since the test statistic falls in the rejection region, we fail to reject the null hypothesis.
