A one-way between-subjects ANOVA was conducted with three groups, and the F_obt value was found to be 4.08. In order to determine the decision at a .05 level of significance, we need to compare the obtained F-value with the critical F-value. Since the question does not provide the critical F-value, we cannot perform this comparison. However, if the obtained F-value is greater than the critical F-value, we would reject the null hypothesis. Therefore, the most appropriate answer is A, reject the null hypothesis.
