The table below presents data from a study investigating the differences between two experimental conditions: the "Foot-in-the-door" condition and a "Control" condition. Each column represents the scores from subjects in each condition.
| Foot-in-the-Door Condition | Control Condition |
|---------------------------|-------------------|
| 87 | 86 |
| 98 | 73 |
| 75 | 79 |
| 88 | 56 |
| 66 | 72 |
| 85 | 70 |
| 92 | 87 |
| 56 | 59 |
| 89 | 64 |
| 85 | 77 |
| 84 | 74 |
| 92 | 72 |
#### Task
Use the eight-step process to test the null hypothesis that there is no difference between the two conditions. Analyze the data to determine if the groups differ significantly.
This dataset is used to apply statistical testing methods that help in examining whether the observed differences between the two conditions are statistically significant or if they occurred by chance. Consider applying appropriate statistical tests to assess the hypothesis.

**Study Overview:**
Using the door-in-the-face technique (a psychological strategy that is effective 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, the researcher asks 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):
**Data Table:**
| Foot-in-the-door condition | Control condition |
|----------------------------|-------------------|
| 87 | 86 |
| 98 | 73 |
| 75 | 79 |
| 88 | 56 |
| 76 | 72 |
| 85 | 70 |
| 92 | 87 |
The table illustrates the amount of money donated by participants under two different conditions: "Foot-in-the-door" and "Control." Each number represents the dollars donated under each respective condition for different participants.
