Prueba de hipótesis

The Power of a test is the probability of the test correctly rejecting a false null hypothesis. How can you increase the power of a test?
  1. You can hope for an extreme sample (drag point A to the right).
  2. You can increase the alpha level, thus increasing the probability of rejecting the null hypothesis regardless of it being false or not (drag point B to the left).
  3. You can increase the sample size (as long as it stays less than 10% of the population size).
