Question: Why are larger samples better? Statisticians prefer large samples. Describe briefly the effect of increasing the size of a sample (or the number of subjects in an experiment) on each of the following:

1. The margin of error of a 95% confidence interval.
2. The P-value of a test, when H ₀ is false and all facts about the population remain unchanged as n increases.
3. The power of a fixed level \(\alpha \) test, when \({{H}_{A}}\), the alternative hypothesis, and all facts about the population remain unchanged.
