- High power is not necessary.
- High statistical power (e.g., 80% or 90%) is critically needed.
- The power should be as low as possible.
- Power is only relevant for large differences.

- Small sample size makes the finding more reliable.
- Small sample size can lead to unstable estimates and findings that may not replicate in larger studies.
- The p-value is always accurate regardless of sample size.
- The study had high power.

- The null hypothesis assumes the new drug is inferior by a pre-specified margin.
- The null hypothesis assumes the new drug is superior.
- The significance level is ignored.
- Non-inferiority trials do not use hypothesis testing.
