A statistical power of 95% implies that O the chance that the alternative hypothesis is true is 95%. O the p-value for the study will be 5%. O Ho is probably false. O it is very likely that Ho will be rejected if it is not true.

Question
**Title: Understanding Statistical Power**

**A statistical power of 95% implies that:**

- ☐ the chance that the alternative hypothesis is true is 95%.
- ☐ the p-value for the study will be 5%.
- ☐ \(H_0\) is probably false.
- ☑ it is very likely that \(H_0\) will be rejected if it is not true.

**Explanation:**

Statistical power is the probability that a test will reject a false null hypothesis (\(H_0\)). A 95% power indicates that there is a 95% chance of correctly rejecting \(H_0\) when it is indeed false. Power is primarily a function of the significance level, sample size, and effect size.
