Suppose that you want to test for a difference in proportion between two groups. Group 1 has 80 respondents and 40% of them like a new product, while Group 2 has 60 respondents and 25% of them like this new product. If the standard error of the difference between proportions is 0.08, the Z-test value for these data is approximately.
