A school district has four schools, six class in from each school were randomly selected and the number of students in the class were recorded. Test the claim that at least one school has a different class size at a 0.01 level of significance.

(claim) a = 0.01 Complete the ANOVA table below: (round answers to 3 decimal places) SS df MS F p-value Between Within The decision of the test is to: O do not reject Ho O reject Ho The final conclusion is: O There is enough evidence to reject the claim that at least one school has a different class size. There is enough evidence to support the claim that at least one school has a different class size. O There is not enough evidence to support the claim that at least one school has a different class size. O There is not enough evidence to reject the claim that at least one school has a different class size.

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.
