It checks if the difference between the proportions of two groups is statistically significance, based on the sample proportions. Web the z test for proportions uses a normal distribution. Z ∗ = p ^ 1 − p ^ 2 − 0 p ^ ∗ ( 1 − p ^ ∗) ( 1 n 1 + 1 n 2).where p ^ ∗ = x 1 + x 2 n 1 + n 2. Web this section will look at how to analyze a difference in the proportions for two independent samples. This tutorial explains the following:
N 1 = sample 1 size. N 1 p ^ 1, n 1 ( 1 − p ^ 1), n 2 p ^ 2, and n 2 ( 1 − p ^ 2) are all greater than five. Conditions required to conduct two proportion z test. P 1 = sample 1 proportion.
