7. Test the null hypothesis of independence of the two classifications A and B of the accompanying contingency table. Use α = 0.05.
1 Click the icon to view the table.
Specify the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: The row and column classifications are dependent
H₁: The row and column classifications are independent
O B. Ho: The row and column classifications are independent
H: The row and column classifications are dependent
O C. Ho: The classifications A₁ and B₁ are independent
H: The classifications A, and B, are dependent
Find the test statistic.
x² = |
(Round to the nearest hundredth as needed.)
Specify the rejection region. Choose the correct answer below.
OA. ²>3.84146
O B. x² > 15.5073
OC. 2>9.48773
O D. x² >16.9190
State the conclusion. Choose the correct answer below.
O A. Fail to reject Ho, there is insufficient evidence to indicate the row and column classification are dependent at a = 0.05.
O B. Reject Ho, there is insufficient evidence to indicate the row and column classification are dependent at a = 0.05.
O C. Reject Ho, there is sufficient evidence to indicate the row and column classification are dependent at a = 0.05.
O D. Fail to reject Ho, there is sufficient evidence to indicate the row and column classification are dependent at a = 0.05.
