### 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.

A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…
Perform a statistical analysis / test of hypothesis Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table. Student Pair 1 2 3 4 5 6 7 8 9 10 Reading Score under Computer Method 85 80 95 87 78 82 57 69 73 99 Reading Score under phonics method 80 80 88 90 72 79 50 73 78 95 Test whether there is a significant difference between the computer method and the phonics method.
