Extracted text: Researchers conducted a study to compare the effectiveness of two pain medications on patients who had been complaining of a certain kind of joint pain. They were interested in the difference in the proportions of patients for who these medications were effective. They gave the medication A to a random sample of 71 patients, and gave medication B to another sample of 66 patients. Based on the sample data, they got a point estimate of 0.059 with a standard error of 0.019. Construct a 95% two-sided confidence interval for the difference in proportions and put its lower endpoint into the box below.
