Exam 12: Analysis of Variance: One-Way Between-Subjects Design

A researcher conducts two studies on child health.In Study 1,30 children consume either a low-,moderate-,or high-fat meal (n = 10 per group).In Study 2,the researcher conducts the same study,except that a No Meal control group is added,with n = 10 in each group.If F_obt = 3.11 in both studies,then in which study will the decision be to reject the null hypothesis at a .05 level of significance for a one-way between-subjects ANOVA?
