Twelve volunteers were assigned to each of three weight-reducing plans. The assignment 6. of the volunteers to the plans was at random, and it was assumed that the 36 volunteers in all would resemble a random sample of people who might try a weight-reducing program. Test the null hypothesis that there is no difference in the probability distributions of the amount of weight lost under the three programs against the alternative that there is a difference. The results are given as the number of pounds lost by each person.

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 re…

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.
