Question

A 3x3 contingency table produced a chi-squared = 6.5. In evaluating the relationship between the variables in the table at the .05 level of significance, the conclusion should be ________.

A. accept the null hypothesis

B. reject the null hypothesis

C. the magic number is 3.84

D. alpha = level of significance =1.96

E. alpha = level of significance = .10

Answer 1

Chi squared value = 6.5 .

Alpha =0.05 .

Degrees of freedom are (3-1)*(3-1)=4

Hence chi squared critical value = 9.488.

Here chi squared value is less than chi square critical value hence WE ACCEPT H0.

Option A is correct.. Accept the null hypothesis.
