An analysis of variance produces SS_between = 30,SS_within = 60,and an F-ratio with df = 2,15.For this analysis,what is the F-ratio? A)30/60 = 0.50 B)60/30 = 2.00 C)15/4 = 3.75 D)4/15 = 0.27

The F-ratio is the ratio of the between-group variability to the within-group variability, which is calculated as SS_between / SS_within. Therefore, the F-ratio = 30/60 = 0.50. However, the question also states that the F-ratio has df = 2,15, which means that the numerator degrees of freedom is 2 and the denominator degrees of freedom is 15. Therefore, we cannot simply report the value of the F-ratio calculated from the Sums of Squares. Instead, we need to compare the calculated F-ratio to the critical F-value for the given degrees of freedom at the desired significance level. This can be done using a table of F-distributions or statistical software. The critical F-value will tell us whether the observed F-ratio is statistically significant, and we can interpret the results accordingly. Since we do not have information about the significance level or the critical F-value in this question, we cannot give a definitive answer about the best choice, but the only choice that correctly calculates the F-ratio is C.
