0,5

5

15

0,7

0,35 


Yanıt Açıklaması:

The test statistic for a one-way ANOVA test is the ratio of two variances; namely the variance between samples (MSB) and variance within samples (MSW). Then, the test statistic F can be obtained as follows, F = MSB / MSW.  

Then, 

F = 350/70 = 5 . The correct answer is B.
