Suppose the results indicate that the null hypothesis should not be rejected; thus, it is possible that a type II error has been committed. Given the type of error made in this situation, what could researchers do to reduce the risk of this error?

Choose a .01 significance level, instead of a .05 significance level.
Increase the sample size.
