19. A study was done to see whether participants would ignore a sign that said, "Elevator may stick between floors. Use the stairs." There were three different situations, two of which involved confederates. A confederate (Conf) is a person who is secretly working with the experimenter. In the first situation, there was no other person using the stairs or elevator-that is, no confederate. In the second, there was a compliant confederate (one who used the stairs). In the third, there was a noncompliant confederate (one who used the elevator). A summary of the data is given in the accompanying table. Complete parts a through c. 1 Click here to view the data. a. Find the percentage of participants who used the stairs in all three situations. What do these sample percentages say about the relationship between compliance and the existence of confederates? Of the no confederate group, Of the compliant confederate group, Of the noncompliant confederate group, (Round to two decimal places as needed.) O O % used the stairs. % used the stairs. % used the stairs. What do these sample percentages say about the relationship between compliance and the existence of confederates? A. The percentages suggest that subjects are influenced by the confederates to not do the same thing. B. The percentages suggest that subjects are influenced by the confederates to do the same thing. C. The percentages do not provide a pattern between compliance and the existence of confederates. D. The percentages suggest that the subjects were not influenced by the confederates. b. From the figure, is the p-value 5.79? Explain. If not, report the actual p-value. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. No, this figure gives the number in a form of scientific notation. The actual p-value is (Round to five decimal places as needed.) O B. Yes, this is the p-value. - Test x = 19.51477833 p 5.7859089E-5 df = 2 c. Determine whether there is a relationship between the three treatment situations and whether the participant used the stairs (was compliant) or not. Use a significance level of 0.05. Choose the correct null hypothesis (Ho) and alternative hypothesis (HA). OA. Ho: Treatment and compliance have non-equal proportions. HA: Treatment and compliance have equal proportions. OB. Ho: Treatment and compliance are independent. HA: Treatment and compliance are not independent. C. Ho: Treatment and compliance have equal proportions. HA: Treatment and compliance have non-equal proportions. D. Ho Treatment and compliance are not independent. HA: Treatment and compliance are independent. Choose the correct conclusion. O A. Fail to reject Ho and conclude that treatment and compliance are not related. B. Reject Ho and conclude that treatment and compliance are related. C. Fail to reject Ho and conclude that treatment and compliance are related. D. Reject Ho and conclude that treatment and compliance are not related. 1: Data Table Used Stairs Used Elevator No Conf 7 Compliant Conf Noncompliant Conf 17 4 12 2 15
