Suppose 13% of American adults believe that the highest priority of America is to protect freedom of speech. We will take a random sample of 20 American adults and ask them the question. Then the sampling distribution of the sample proportion of people who answer yes to the question is:
A. approximately Normal, with mean 0.13 and standard error 0.0238
B. approximately Normal, with unknown mean and standard deviation.
C. Binomial, with n=200 and p=0.13.
D. neither Normal, not Binomial.
