Suppose that 50 % of Americans drink soda every day. Amy, a researcher at a local university, takes a random sample of 16 Americans. Let ???? represent the number of Americans in Amy's sample who drink soda every day. Let ???? and ???? represent the parameters of a normal distribution and let ???? and p represent the parameters of a binomial distribution. The sampling distribution of ???? is : almost binomial with ????=16 and p=0.5 . exactly normal with ????=8 and ????=2.000 . exactly binomial with ????=16 and p=0.5 . a approximately normal with ????=0.5 and ????=0.125 .
