Question

You are conducting a test of the claim that the row variable and the column variable are dependent in the following contingency table.

	X	Y	Z
A	53	38	24
B	39	35	7

Give all answers rounded to 3 places after the decimal point, if necessary.

(a) Enter the expected frequencies below:

	X	Y	Z
A
B

(b) What is the chi-square test-statistic for this data?
Test Statistic: χ2=

(c) What is the critical value for this test of independence when using a significance level of αα = 0.005?
Critical Value: χ2=

(d) What is the correct conclusion of this hypothesis test at the 0.005 significance level?
