Which two results occur when the null hypothesis is accepted using an F-test?

Choose 2 answers.

AThe test statistic is less than the critical value.

BThe test statistic is greater than the critical value.

CThere appears to be a difference between the two samples.

DThere appears to be no difference between the two samples.

Suggested Answer: A, D

When the null hypothesis is accepted in an F-test, it indicates that there is no statistically significant difference between group variances or means, depending on the test design. Acceptance occurs when the test statistic is less than the critical value, meaning the observed variation is within expected limits.

Accepting the null hypothesis implies that no meaningful difference exists between the samples. If the test statistic exceeded the critical value, the null hypothesis would be rejected.

Thus, the correct results are A and D.

Macy 2 months ago

Exactly! If the test statistic is less, we accept it.

I keep mixing up the terms, but I think accepting the null means we don't find evidence for a difference, so maybe D is right?

Evan 6 months ago

I practiced a similar question, and I feel like A and D are the right choices since they both suggest no significant difference.

Ronny 6 months ago

I'm not entirely sure, but I remember something about accepting the null indicating no significant difference, which could relate to D.

Eric 6 months ago

I think if we accept the null hypothesis, it means the test statistic is less than the critical value, so A might be correct.
