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 | 25 | 33 | 33 | | B | 27 | 36 | 40 | 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 α = 0.025? Critical Value: χ² = [ ] (d) What is the correct conclusion of this hypothesis test at the 0.025 significance level? - There is not sufficient evidence to support the claim that the row and column variables are dependent. - There is not sufficient evidence to warrant rejection of the claim that the row and column variables are dependent. - There is sufficient evidence to warrant rejection of the claim that the row and column variables are dependent. - There is sufficient evidence to support the claim that the row and column variables are dependent. **Remember to give all answers rounded to 3 places after the decimal point, if necessary.**
