The df value for a chi-square test for independence is calculated by taking the product of the number of categories for each variable and subtracting it by 1. In this case, there are 3 categories for birth-order position (1st, 2nd, and 3rd) and 2 categories for self-esteem (high and low), so the df value is (3 x 2) - 1 = 5 - 1 = 4. Therefore, the correct answer is D.
