In: Statistics and Probability
You are conducting a test of the claim that the row variable and the column variable...
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 | 16 | 22 | 18 |
| B | 34 | 39 | 10 |
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=χ2=
(c) What is the critical value for this test of
independence when using a significance level of αα = 0.01?
Critical Value:
χ2=χ2=
(d) What is the correct conclusion of this hypothesis test at the 0.01 significance level?
- 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 sufficient evidence to warrant rejection of 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.
