You are conducting a test of the claim that the row variable and the column variable are dependent in the following contingency table. A 42 12 27 B 25 43 30 Give all answers rounded to 3 places after the decimal point, if necessary. (a) Enter the expected frequencies below: A XYZ X Y Z B X Y Z (b) What is the chi-square test-statistic for this data? Test Statistic: x² = (c) What is the critical value for this test of independence when using a significance level of a = 0.05? Critical Value: x² (d) What is the correct conclusion of this hypothesis test at the 0.05 significance level? There is sufficient evidence to support the claim that the row and column variables are dependent. O There is not sufficient evidence to warrant rejection of the claim that the row and column variables are dependent. O There is sufficient evidence to warrant rejection of the claim that the row and column variables are dependent.
