Question

Construct a confidence interval for p 1 minus p 2 at the given level of confidence. x 1 equals366, n 1 equals509, x 2 equals404, n 2 equals554, 90% confidence The researchers are nothing% confident the difference between the two population proportions, p 1 minus p 2, is between nothing and nothing.

Answer #1

Given that, x1 = 366, n1 = 509 and x2 = 404, n2 = 554

Using TI-84 calculator get, the 90% confidence interval for (p1 - p2) is, (-0.0553, 0.0350).

The researchers are **90%** confident the
difference between the two population proportions, (p1- p2) , is
between **-0.0553** and **0.0350**

Construct a confidence interval for p 1 minus p 2 at the given
level of confidence. x 1 equals 386, n 1 equals 516, x 2 equals
411, n 2 equals 595, 90 % confidence The researchers are nothing
% confident the difference between the two population
proportions, p 1 minus p 2 , is between nothing and nothing .
(Use ascending order. Type an integer or decimal rounded to three
decimal places as needed.)
