find the rejection region for a test of independence of two

find the rejection region for a test of independence of two classifications where the contingency table contains r =2 and c = 4 columns and = .10

A) x2> 22.307 B) x2 > 6.251 C) x2 > 15.507 D) x2> 13.362

^2 degrees of freedom = ( r-1 ) * (c-1) = (2-1) * (4-1) = 1 * 3 = 3
At 0.10 LOS , ^2 test statistic for 3 degrees os freedom is 6.251

[ANSWER ] ^2 degrees of freedom = ( r-1 ) * (c-1) = (2-1) * (4-1) = 1 * 3 = 3
At 0.10, ^2 test statistic for 3 degrees os freedom is 6.251
