A researcher conducts a 2 * 4 between-subjects ANOVA in which 12 participants were observed in each group.If SS_B = 18 and SS_E = 264 for this study,then what is the decision for Factor B at a .05 level of significance? A) reject the null hypothesis B) retain the null hypothesis C) there is not enough information to answer this question

To determine the decision for Factor B, we calculate the F-ratio for Factor B. The formula for the F-ratio is F = MSB/MSE, where MSB is the mean square between groups for Factor B, and MSE is the mean square error. Given SSB = 18 and SSE = 264, we first need to calculate MSB and MSE. However, without the degrees of freedom for both SSB and SSE, we cannot calculate the F-ratio accurately. Since the degrees of freedom are not provided, and they are essential for calculating the F-ratio and making a decision regarding the null hypothesis, we do not have enough information to make a decision about Factor B. Therefore, we retain the null hypothesis due to insufficient information to properly conduct the test.
