Suppose that 75% of adult Americans agree that, while downloading music from the Internet and then selling it is piracy and should be prohibited, downloading for personal use is an innocent act and should not be prohibited. We will take a random sample of 50 American adults and ask them if they agree with the statement. Then the sampling distribution of the sample proportion of people who answer yes to the question is:
A) approx normal with mean of .75 and standard error .0612
B) approx normal with unknown mean and standard deviation
C) binomial with n=50 and p=.75
D) neither normal or binomial
