A recent Gallup poll consisted of


939


randomly selected adults who were asked whether​ "cloning of humans should or should not be​ allowed." Results showed that


803





of those surveyed indicated that cloning should not be allowed. Construct a​ 99% confidence interval estimate of the proportion of all people who say they are opposed to cloning.





a. What is the sample​ size? n​ = nothing




b. Calculate the sample​ proportion:
ModifyingAbove p with caret equals


nothing




​(round to 3 decimal​ places)


c. Calculate
ModifyingAbove q with caret equals


nothing




​(round to 3 decimal​ places)


d. What is the critical​ value?
z Subscript alpha divided by 2 Baseline equals


nothing




​(use 3 decimal​ places)


e. Calculate the margin of​ error: E​ =
nothing




​(round to 3 decimal​ places)


f. Find the confidence​ interval:
nothing


less than p less thannothing




​(round to 3 decimal​ places)


g. Do your results suport the claim that a majority of adults are opposed to such​ cloning? Why or why​ not?











A.


​Yes, because
ModifyingAbove p with caret







is close to 0.5








B.


​No, because
ModifyingAbove p with caret







is greater than 0.5









C.


​No, because the lower confidence interval limit is above 0.5








D.


​Yes, because the lower confidence interval limit is above 0.5
