In a test of weight loss programs, 170 subjects were divided such that 34 subjects followed each of 5 diets. Each was weighed a year after starting the diet and the results are in the ANOVA table below. Use a 0.05 significance level to test the claim that the mean weight loss is the same for the different diets. Source of Variation Between Groups Within Groups F crit 2.426438 df MS F P-value 72.209 5438.420 5510.629 18.05226 0.5477 0.700949 165 32.96012 169 4 Total Should the null hypothesis that all the diets have the same mean weight loss be rejected? A. Yes, because the P-value is less than the significance level. O B. No, because the P-value is less than the significance level. OC. No, because the P-value is greater than the significance level. O D. Yes, because the P-value is greater than the significance level.
