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 0.025 significance level to test the claim that the mean weight loss is the same for the different diets. df MS P-value F crit Source of Variation Between Groups Within Groups 130.35122 3.8443 0.005237 2.869395 521.405 5255.687 155 33.90766 Total 5777.092 159 Should the null hypothesis that all the diets have the same mean weight loss be rejected? O A. No, because the P-value is greater than the significance level. B. Yes, because the P-value is less than the significance level. O C. Yes, because the P-value is greater than the significance level. O D. No, because the P-value is less than the significance level.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
