In testing the independence of two variables described in a contingency table, determine the critical value of chi-square if the test is to be conducted at the
a. x = 0.025 level and df = 5
b. x = 0.05 level and df = 8
c. x = 0.01 level and df = 6
d. x = 0.10 level and df = 4
The solution provides step by step method for the calculation of a chi square statistic. The formula for the calculation and interpretations of the results are also included.
