Transcribed Image Text:## Study of Impulse Control in Grade School Children
**Background:**
Wilson (1999) conducted a study on impulse control among grade school children. The research involved two groups of third graders:
1. **Average Third Graders:**
- **Sample Size:** 25 students
- **Average Failures of Impulse Control:** 4.6 times per day
- **Standard Deviation:** 2.1 times per day
2. **Third Graders Diagnosed with ADHD:**
- **Sample Size:** 36 students
- **Average Failures of Impulse Control:** 7.2 times per day
- **Standard Deviation:** 3.1 times per day
**Objective:**
To determine if third graders with ADHD experience more difficulty with impulse control compared to their peers without ADHD.
**Statistical Analysis:**
- **Significance Level (α):** 0.05
- **Test Type:** Two-tailed test
**Task:**
Complete all four steps of hypothesis testing to assess whether the impulse control in third graders with ADHD is significantly different from those without ADHD.
