Question

You complete a hypothesis test using a = .05, and based on the evidence from the sample, your decision is to reject the null hypothesis. If the treatment actually has no effect, which of the following is true?​

Group of answer choices

​You have made a Type I error.

​You have made a Type II error.

​You might have made a Type I error, but the probability is only 5% at most.

​You have made the correct decision.

​For a repeated-measures study, as the sample mean difference increases, the likelihood of rejecting the null hypothesis also increases.

True

False

Answer 1

You complete a hypothesis test using a = .05, and based on the evidence from the sample, your decision is to reject the null hypothesis. If the treatment actually has no effect.

That means we are rejecting null when it is true...

So we have made a type I error(Ans)

​For a repeated-measures study, as the sample mean difference increases, the likelihood of rejecting the null hypothesis also increases.

This is true(ans)

Reason-as sample mean difference increases that is tending to rejection region as value of test statistic increases.....
