Question 5 (1.25 points) Match each of the following: Rejecting Ho when it is false Failing to reject Ho when it is true 1. Type 1 Error Correct Decision Failing to reject Ho when it is false 3. Type II Error Rejecting Ho when it is true
When thinking about statistical hypothesis testing, power is A. the probability that the null hypothesis is true. B. the probability that the null hypothesis is false. C. the probability a false null hypothesis will be rejected. D. the probability a true null hypothesis will be rejected.
What can be concluded by failing to reject the null hypothesis? A. either that the null hypothesis is correct or that the test procedure is not strong enough (i.e. that the sample size is not large enough) to reject the null hypothesis B. that the null hypothesis is correct, therefore the alternative hypothesis should be rejected C. that the function of the alternative hypothesis is incorrect D. that the alternative hypothesis is correct, therefore the null hypothesis should be rejected
