Question

Construct a confidence interval for $p_1 - p_2$ at the given level of confidence. $x_1 = 30$, $n_1 = 268$, $x_2 = 32$, $n_2 = 294$, 90% confidence The researchers are % 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

$\hat{p_1}=\frac{x_1}{n_1}=\frac{30}{268}=0.112$ $\hat{p_2}=\frac{x_2}{n_2}=\frac{32}{294}=0.109$ Show more…
