Company A is trying to sell its website to Company B. As part of the sale, Company A claims that the average user of their site stays on the site for 10 minutes. Company B is concerned that the mean time is significantly less than 10 minutes. Company B collects the times (in minutes) below for a sample of 18 users. Assume normality. 94.725.24.40.40.519.68.65.12.11.11. 95.54.720.20.80.30.5

Required:
Conduct the appropriate hypothesis test for Company B using a 0.08 level of significance.

a. What is the critical value for the test? Give your answer to four decimals.

b. What is the appropriate conclusion?
1. Reject the claim that the mean time is 10 minutes because the test statistic is larger than the critical point.
2. Fail to reject the claim that the mean time is 10 minutes because the test statistic is larger than the critical point.
3. Reject the claim that the mean time is 10 minutes because the test statistic is smaller than the critical point.
4. Fail to reject the claim that the mean time is 10 minutes because the test statistic is smaller than the critical point.
