Question

In a study, group A had x1=132 $$x_1 = 132  $$successes out of n1=600 $$n_1 = 600$$ , and group B had x2=95 $$x_2 = 95  $$successes out of n2=480 $$n_2 = 480 . $$Construct a 98%98\% confidence interval for p1−p2 $$p_1$$ - $$p_2 .$$

Accepted Answer

(−0.0356,0.0798)\left(-0.0356,0.0798\right)

Answer

(−0.0301,0.0837)(-0.0301, 0.0837)

Answer

(−0.0452,0.1023) (-0.0452, 0.1023)

Answer

(−0.0215,0.0951)(-0.0215, 0.0951)

In a study, group A had x1=132 x_1 = 132 successes out of n1=600 n_1 = 600 , and group B had x2=95 x_2 = 95 successes out of n2=480 n_2 = 480 . Construct a 98%98\% confidence interval for p1−p2 p_1 - p_2 .

In a study, group A had $x sub 1 equals 132$ successes out of $n sub 1 equals 600$ , and group B had $x sub 2 equals 95$ successes out of $n sub 2 equals 480$ . Construct a $98 percent sign$ confidence interval for $p sub 1 minus p sub 2$ .
