This problem demonstrates a possible (though rare) situation that can occur with group comparisons. The groups are sections and the dependent variable is an exam score. Section 1 Section 2 Section 3 71.5 51.4 65.6 67.8 45.1 60.7 55.2 44.2 62.1 54.1 55.2 54.4 62.1 50 50.7 57.2 31 58.9 65.8 67.1 52.4 47.4 28.4 68.1 63 70.7 61.5 Run a one-way ANOVA (fixed effect) with a - 0.05. Round the F-ratio to three decimal places and the p- value to four decimal places. Assume all population and ANOVA requirements are met. P What is the conclusion from the ANOVA? O reject the null hypothesis: at least one of the group means is different O fail to reject the null hypothesis: not enough evidence to suggest the group means are different
