A researcher looks at the mean salaries of male and female electricians and decides based on the evidence that there is no difference between the two groups. Given that there was a failure to reject the null hypothesis, it is possible that a type II error was made. 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.
