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 | 38 | 36 | 44 |
| B | 39 | 36 | 31 |
The chi-square test-statistic for this data is 1.628.
The critical value for this test of independence when using a significance level of αα = 0.005 is χ2=χ2= 10.597.
What is the correct conclusion of this hypothesis test at the 0.005 significance level?
- There is sufficient evidence to warrant rejection of the claim that the row and column variables are dependent.
- There is not sufficient evidence to support 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.
- There is not sufficient evidence to warrant rejection of the claim that the row and column variables are dependent.
Homework Answers
Chi square test statistic =1.628 < Chi square critical value =10.597
Therefore, we fail to reject H0
| There is not sufficient evidence to support the claim that the row and column variables are dependent. |
