6. +-/8 points BBBasicStat8 9.1.016. My Notes + Ask Your Teacher 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 female companion: 8.3 min. 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. (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: u = 8.3; H1: u 8.3 o Ho: u 8.3 o Ho: H = 8.3; H1: u # 8.3 o Ho: H = 8.3; H1: H 4.5; H1: u = 4.5 Ho: H = 4.5; H1: u + 4.5 o Ho: H = 4.5; H1: H > 4.5 Is this a right-tailed, left-tailed, or two-tailed test? o left-tailed right-tailed two-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? Ho: u # 4.5; H1: u = 4.5 o Ho: H = 4.5; H1: u 4.5 Ho: H = 4.5; H1: u # 4.5 Is this a right-tailed, left-tailed, or two-tailed test? right-tailed o left-tailed two-tailed Need Help?
