Before performing a Chi-Square test of independence, let's verify that the four assumptions of the test are met. Assumption 1: Both variables are categorical. This assumption is easy to verify. We can see that the two variables in the contingency table are both categorical: Gender: This variable can only take on two categories - Male or Female.

It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2)) Large Counts Condition (one-sample) To check that the sampling distribution of p-hat is approximately normal, check that both the number of successes (n x p-hat) and the number of failures (n x (1-p-hat)) are at least 10 so that the sample size is large enough to support an assumption of normality
