Suppose you want to set up a statistical test to challenge the claim that a woman with a female friend spends an average of 8.3 minutes shopping in such a store. (a) What would you use for the null and alternate hypotheses if you believe the average shopping time is less than 8.3 minutes? Ho: ? = 8.3; H1: ? ≠ 8.3Ho: ? < 8.3; H1: ? = 8.3 Ho: ? = 8.3; H1: ? < 8.3Ho: ? = 8.3; H1: ? > 8.3 Is this a right-tailed, left-tailed, or two-tailed test? right-tailedtwo-tailed left-tailed (b) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 8.3 minutes? Ho: ? = 8.3; H1: ? > 8.3Ho: ? ≠ 8.3; H1: ? = 8.3 Ho: ? = 8.3; H1: ? < 8.3Ho: ? = 8.3; H1: ? ≠ 8.3 Is this a right-tailed, left-tailed, or two-tailed test? left-tailedtwo-tailed right-tailed Stores that sell mainly to women should figure out a way to engage the interest of men! Perhaps comfortable seats and a big TV with sports programs. Suppose such an entertainment center was installed and you now wish to challenge the claim that a woman with a male friend spends only 4.5 minutes shopping in a houseware store. (c) What would you use for the null and alternate hypotheses if you believe the average shopping time is more than 4.5 minutes? Ho: ? = 4.5; H1: ? > 4.5Ho: ? > 4.5; H1: ? = 4.5 Ho: ? = 4.5; H1: ? < 4.5Ho: ? = 4.5; H1: ? ≠ 4.5 Is this a right-tailed, left-tailed, or two-tailed test? two-tailedleft-tailed right-tailed (d) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 4.5 minutes?

How much customers buy is a direct result of how much time they spend in the store. A study of average shopping times in a large national houseware store gave the following information (Source: Why We Buy: The Science of Shopping by P. Underhill).
Women with male companion: 4.5 min.
Suppose you want to set up a statistical test to challenge the claim that a woman with a female friend spends an average of 8.3 minutes shopping in such a store.
Is this a right-tailed, left-tailed, or two-tailed test?
(b) What would you use for the null and alternate hypotheses if you believe the average shopping time is different from 8.3 minutes?
Is this a right-tailed, left-tailed, or two-tailed test?
