Please help! It would be greatly appreciated!
In a test of weight loss programs, 160 subjects were divided such that 32 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 df MS P-value F crit 629.333 4 57.33332 4.9031 0.000948 2.430002 4973.724 155 32.08854 Should the null hypothesis that all the diets have the same mean weight loss be rejected? O A. No, because the P-value is less than the significance level. O B. Yes, because the P-value is greater than the significance level. C. Yes hecause th? P-value is less than the sianificance levelExplanation / Answer
since p-value(0.000948) which is less than the level of significance(0.05) and in this case, we reject the null hypothesis. and Hence, option(c),(Yes, because the p-value is less than the significance level) is correct.
