Use the contingency table to the right to calculate the marg

Use the contingency table to the right to calculate the marginal frequencies and find the expected frequency for each cell in the contingency table. Assume that the variables are independent (a) Calculate the marginal frequencies and sample size. (b) Find the expected frequency for each cell in the contingency table. (Round to two decimal places as needed.)

Solution

Null hypothesis:

H0: All Means are equal

Ha: atleast two means are not equal

Two tailed chi square test

Prepare contingency table

chi-square = 27.0
degrees of freedom = 2
