Which of these strategies is MOST commonly used to decrease the probability of making a type II error?
A) never rejecting the null hypothesis
B) increasing the sample size
C) lowering alpha
D) increasing the probability of making a type I error

Increasing the sample size helps decrease the probability of making a type II error by making the results more representative of the population, reducing the variability and increasing the power of the study. This allows for a better chance of detecting a true difference if it exists. The other options, such as never rejecting the null hypothesis or increasing the probability of making a type I error, do not address the issue of type II errors directly and may lead to other problems in statistical inference. Lowering alpha may reduce the probability of a type I error, but it does not necessarily improve the chances of detecting a true effect.
