Question

Construct a confidence interval for p1 - p2 at the given level of confidence. x1 = 364, n1 = 518, x2 = 445, n2 = 555, 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

p1 = X1 / n1 = 364 / 518 = 0.7027 p2 = X2 / n2 = 445 / 555 = 0.8018 Show more…
