Using the door-in-the-face technique (a psychological technique that works because participants are more likely to comply with a small request after first rejecting a large request), a researcher asks participants in the door-in-the-face condition to volunteer two weeks of their time to help out at a summer camp for impoverished children. When, as expected, they decline this large request, he asks them if they would be willing to donate money to the camp instead (the small request). For participants in the control condition, the researcher asks them to donate money (the small request) without mentioning the two-week volunteer time. This is your data (in dollars donated for the camp): Foot-in-the-door condition Control condition 87 86 98 73 75 79 88 56 76 72 85 70 92 87 56 59 89 64 85 77 84 74 92 72 Use the eight steps to test the null hypothesis that there is no difference between the two conditions.
