Suppose you are conducting a test of independence. Specify the critical value under the following scenarios (Use Table 3):

Solution

(a) The degree of freedom =(r-1)*(c-2) = 4*1=4

Given a=0.05, the critical value of X^2 with 0.95 and df=4 is 9.488 (from chisquare table)

-----------------------------------------------------------------------------------------------------------------

(b) The degree of freedom =(r-1)*(c-2) = 1*2=2

Given a=0.1, the critical value of X^2 with 0.9 and df=2 is 9.210 (from chisquare table)
