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 12 32 32
B 31 43 34

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 = 0.05?
      Critical Value: χ2=

(d) What is the correct conclusion of this hypothesis test at the 0.05 significance level?

  • There is sufficient evidence to support 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 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.

Remember to give all answers rounded to 3 places after the decimal point, if necessary.
