### Data Comparison: Foot-in-the-Door vs. Control ConditionThe 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 |#### TaskUse 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. ### Educational Website Content**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.

NFL Pre-Season Does pre-season success indicate regular season success in the US National Football League? We looked at the number of pre-season wins and regular season wins for all 32 NFL teams over a 10 year span. (a) What would a positive association imply about the relationship between pre-season and regular season success in the NFL? O More wins in the pre-season is associated with more wins in the regular season. O More wins in the pre-season is associated with fewer wins in the regular season. O There is almost no association between the number of wins in the pre-season and the number of wins in the regular season. eTextbook and Media (b) What would a negative association imply about the relationship between pre-season and regular season success in the NFL?
