Challenge Problems
Push your limits with advanced challenges
During a clinical trial for a new drug, researchers establish α at 0.05. The p-value obtained is 0.07. What decision should be made regarding the null hypothesis, and what type of error could potentially occur?
💡 Hint: Reflect on the implications of your p-value in relation to the significance level.
In testing a hypothesis about the average test scores of students, a researcher finds that their significance level leads to a 10% Type I error rate. What could be the potential impact of this error on educational policy decisions?
💡 Hint: Consider how policy changes based on faulty data could affect educational stakeholders.
