Stone Alaska Airlines Cheap Airline Tickets Chuck Berry 2016 Crossovers Free Credit Report Minnesota Vikings Answers Relevance Rating Newest Oldest Best Answer: Since your margin of error is 0.05 you need the confidence interval to be ^ p ± 0.05 meaning it would go from 0.10 to 0.20 if p hat were again 0.15 . Since we don't know the population proportion p, we note the mean of p hat is p and the variance is p(1-p)/n and the standard deviation is the square root of that The largest possible value of the variance is 0.5(0.5)/n and the 99 percent confidence interval = p hat ± z(0.005 in right tail) σ{p hat} We need for z(0.005 in right tail) σ{p hat} to equal 0.05 Now z(0.005 in right tail) = z( 0.995 is to left of the given z value ) You can get the negative of this by looking up the z such that Pr(Z≤z) = 0.005 and that is -2.575 . I got it by using =norminv(0.005,0,1) in Microsoft Excel however you can use the z table in the back of your statistics book. Our z is therefore 2.575. Next σ{p hat} = square root o
