In: Statistics and Probability
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 | 20 | 46 | 44 |
B | 20 | 36 | 26 |
Give all answers rounded to 3 places after the decimal point, if necessary.
(a) Enter the expected frequencies below:
X | Y | Z | |
---|---|---|---|
A | |||
B |
To find the expected frequencies:
(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 = 0.10?
Critical Value:
χ2=χ2= (Enter 4.605 as the answer to this question.)
(d) What is the correct conclusion of this hypothesis test at the 0.10 significance level?
Remember to give all answers rounded to 3 places after the decimal point, if necessary.
Conclusion :
There is sufficient evidence to warrant rejection of the claim that the row and column variables are dependent.
Thank You!
