Question

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. n = 62, x = 25; 95% confidence OA) 0.580 < p < 0.596 B) 0.280 < p < 0.526 OC) 0.300 < p < 0.506 OD) 0.281 < p < 0.525 E) 1.280 < p < 2.526 F) 0.301 < p < 0.505

Answer 1

solution Given that, =62, X=25, 95%. Confidence interval for p þ= 0,403 , @= 1 = 1-0.403 @= 0.597 sing z- table at &=5% or 2005 95 % CI for population proposton, P [ P I Za på [01403 196 101403301597] [0-403 01122] [0:403-01122, 01403 +0.122] [0.281, 01525] =) 012812 P201525 option © 01281<$20.525 Zd/2=1196 is correct
