Explain how to find the critical value for an F-test. Choose the correct answer

Question

Explain how to find the critical value for an F-test. Choose the correct answer below. ? A. O B. Specif the level of significance, ? Determine the degrees offreedom for the numerator, d f N and denominator, d D Find the critical value of F using technology or the F-distribution table Specify the level of significance, ?. Use the ratio. , to find the critical value ? C Determine the degrees of freedom for the numerator, d fN and denominator, d f D set e al of the est statist F to in the critical value. ? D, specify the level of significance, ? Use the population variances, ? and ?3 to calculate the critical value of F using technology or the F-distribution table

Explanation / Answer

The critical value depends only on the level of significance and the degrees of freedom. Also the critical value does not depend on the test statistic. Therefore C is FALSE here. Also the sample variances or population variances are used to compute the test statistic and not the critical value. Therefore A should be the correct answer here.

Therefore A is the correct answer here.
