Next THREE questions are based on the following American workers spend an average of 46 minutes to and from work in a typical day.In a sample of n = 104 employed adults in Indianapolis metropolitan area (IMA), the average commuting time to work was x = 50.5 minutes, with s = 24.2 minutes. Is there enough evidence, at = 0.05, to conclude that the average commuting time in IMA is greater than the national average?

9. To perform a hypothesis test, the null and alternative hypotheses for this test are:

a. H: < 46 H: 46

b. H: 46 H: > 46

c. H: 46 H: < 46

d. H: > 46 H: 46

10. For the previous question, the test statistic is |TS| = _______. (if negative, use the absolute value)

a. 1.90 Reject H.Conclude the average commuting time in IMA is greater than the national average.

b. 1.90 DNR H. Do not conclude the average commuting time in IMA is greater than the national average.

c. 2.01 Reject H.Conclude the average commuting time in IMA is greater than the national average.

d. 2.01 DNR H.Do not conclude the average commuting time in IMA is greater than the national average. Conclude the average commuting time in IMA is not greater than the national average.

11. In the previous question the, p-value = ______.

a. 0.0287

b. 0.0201

c. 0.0182

d. 0.0089
