Question

Construct a confidence interval for $p_1 - p_2$ at the given level of confidence. $x_1 = 371, n_1 = 532, x_2 = 433, n_2 = 558, 90%$ confidence The researchers are 90% confident the difference between the two population proportions, $p_1 - p_2$, is between and . (Use ascending order. Type an integer or decimal rounded to three decimal places as needed.)

Step 1

p1 = X1/n1 = 371/532 = 0.697 p2 = X2/n2 = 433/558 = 0.776 Show more…
