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.

The table to the right shows the number of female students who played on a sports team in grades 9 through 12 for a random sample of 6 high schools in a state. At a = 0.10, can you reject the claim that the mean numbers of female students who played on a sports team are equal for all grades? Perform a one-way ANOVA test by completing parts a through d. Assume that each sample is
drawn from a normal population, that the samples are independent of each other, and that the populations have the same variances.

(a) Identify the claim and state Ho and Ha. Choose the correct answer below.
O A. Ho: H1 = H2 = H3 = H4 (claim)
O B. Ho: H1 = H2 = H3 = H4 = H5 = H6
Ha: At least one mean
s different from the others.
Ha: At least one mean is different from the others. (claim)
OC. Ho: At least one mean is different from the others. (claim)
O D. Ho: H1 = H2 =H3 = H4
Ha: H1 = H2 = H3 = H4 = H5 = H6
Ha: At least one mean is different from the others. (claim)
(b) Identify the degrees of freedom for the numerator and for the denominator, determine the critical value, and determine the rejection region.
The degrees of freedom for the numerator, d.f.N,
,is
and the degrees of freedom for the denominator, d.f.p, is
The critical value is Fo =
(Round to two decimal places as needed.)
The rejection region is F |
(Round to two decimal places as needed.)
(c) Calculate the test statistic.
F=
(Round to three decimal places as needed.)
(d) Decide to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim. Choose the correct decision below.
O A. Since F is in the rejection region, reject Ho.
O B. Since F is not in the rejection region, fail to reject Ho:
O C. Since F is not in the rejection region, reject Ho.
O D. Since F is in the rejection region, fail to reject Ho.
Interpret the decision in the context of the original claim.
