A research organization tested microwave ovens. At alpha=.10, is there a significant difference in the average price of the three types of ovens? The data and an ANOVA table are shown below. Based on the ANOVA table is the null hypothesis of equal price rejected or not rejected? On what did you base your decision? Be sure to justify your answer.
