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.

e-22 | 6 | 6 | 1 | 2 | 2 | 3 | 4 | 1 | 6 | 7 | 8 | 9 | 6 | 1 | 5 | 3 | 3 4 5 | 3 | 5 | 0 | 2 | 1 | 1 | 0 | 0 | 1 | 5 | 4 | 1 | 0 | 2 |

conduct the appropriate hypothesis test for company b using a 0.03 level of significance.

a) what are the appropriate null and alternative hypotheses?

h0: μ = 10 versus ha: μ < 10h0: x = 10 versus ha: x ≠ 10 h0: μ = 10 versus ha: μ ≠ 10h0: μ = 10 versus ha: μ > 10

b) what is the test statistic? give your answer to four decimal places.
