Question

Construct a confidence interval for p1 - p2 at the given level of confidence. x1 = 365, n1 = 502, x2 = 433, n2 = 579, 95% confidence The researchers are 95% confident the difference between the two population proportions, p1 - p2, is between and . (Use ascending order. Type an integer or decimal rounded to three decimal places as needed.)

Step 1

First, we need to find the sample proportions: p1 = X1/n1 = 365/502 p2 = X2/n2 = 433/579 Show more…
