eckman hypothesized that experience playing video games would improve a rson's spatial skills. Each participant's spatial skills were measured. Participants en played video games for two hours and their spatial skills were measured again the end of the game. The number of correct spatial problems was recorded for ch participant. Analyze the following data, state your null hypothesis, and report our critical value using a = .05. Interpret your results. Sp = 2.8 %3D %3D Before After 10 M = 5.33 M = 7

Question
**Hypothesis Testing on Video Game Experience and Spatial Skills Improvement** **Research Context:** Beckman proposed a hypothesis that playing video games could enhance a person's spatial skills. To test this hypothesis, the spatial skills of each participant were measured before and after playing video games for two hours. The number of correctly solved spatial problems was recorded. **Data Presentation:** | | Before | After | |------|--------|-------| | **Participant 1** | 7 | 10 | | **Participant 2** | 5 | 6 | | **Participant 3** | 8 | 5 | | **Participant 4** | 3 | 5 | | **Participant 5** | 4 | 7 | | **Participant 6** | 5 | 9 | - **Mean (Before):** 5.33 - **Mean (After):** 7 **Statistical Analysis Requirements:** 1. **Null Hypothesis (H0):** There is no significant difference in spatial skills before and after playing video games. 2. **Alpha Level (α):** 0.05 3. **Standard Deviation (SD):** 2.8 **Analysis Task:** - Calculate the critical value and interpret the results to determine if playing video games significantly affects spatial skills at the 0.05 significance level.
