In a sample of 28 participants,suppose we conduct an analysis of regression with one predictor variable.If F_obt = 4.28,then what is the decision for this test at a .05 level of significance? A) X significantly predicts Y. B) X does not significantly predict Y. C) There is not enough information to answer this question.

Given the F statistic (F_obt = 4.28) for a regression analysis with one predictor and 28 participants, if the F value is significant at the .05 level, it indicates that the predictor variable X significantly predicts the outcome variable Y. The exact critical value for significance depends on the degrees of freedom associated with the F distribution for this test, which are determined by the number of predictors and the sample size. However, without the exact degrees of freedom or the critical F value provided, we typically rely on common critical values for interpretation. An F value of 4.28 generally suggests significance in many contexts at the .05 level, leading to the conclusion that X significantly predicts Y.
