In a two-tailed F-test about equality of two population variances, given n1=21, S21 = 8.2, n2=26, S22= 4.0, and alpha = 0.05. The numerator and denominator degrees of freedom for the F distribution, respectively, are A. 21 and 26 B. 26 and 21 C. 20 and 25 D. 27 and 22
Finding F critical for Variances Use the F-distribution to find the degrees of freedon for the numerator (d.f.N.), the degrees of freedom for the Denominator (d.f.D.) and the critical F-value Use the closest value when looking up the d.f.N. and d.f.D. in the tables.

A. Critical Values for Hypothesis Tests (o known) a) For an upper tailed hypothesis test when a = .0197, then 2 = b) For a two-tailed hypothesis test when a = 0.0104, then 2a/2= c) For a lower-tailed hypothesis test when a = 0.0132, then-Za = B. Critical Values for Hypothesis Tests (o unknown) a) For an upper tailed hypothesis test at 27 d.f. and a = .025, then ta = b) For a two-tailed hypothesis test at 58 d.f....
In a difference of proportion test with alpha = .05, the critical values(s) for a two-tailed test is/are -2.575 and 2.575 1.96 -1.645 and 1.645 -1.96 and 1.96 If the test statistic for a difference of means test has a p-value of .065, we could reject the Null Hypothesis at an alpha level of.10. True False
