Question

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  37   41   11 
B  54   31   23 

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 = 0.10?
      Critical Value: χ2=

(d) What is the correct conclusion of this hypothesis test at the 0.10 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 not sufficient evidence to warrant rejection of 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.
