Question

Construct a confidence interval for p1 - p2 at the given level of confidence. x1 = 382, n1 = 541, x2 = 431, n2 = 554, 90% confidence The researchers are []% 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

Given: - Sample 1: X1 = 382, n1 = 541 - Sample 2: X2 = 431, n2 = 554 Sample proportion for Sample 1 (p1): p1 = X1 / n1 p1 = 382 / 541 p1 ≈ 0.7061 Sample proportion for Sample 2 (p2): p2 = X2 / n2 p2 = 431 / 554 p2 ≈ 0.7780 Show more…
