Your publishing company conducts it’s own survey of a random sample of 250 Americans 16 years old or older. What is the probability that more than 54% in your sample read at least 6 books within that last year? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! use z
z>=(0.54-0.46)/sqrt(.46*.54/250); sqrt =0.0315
z>= 0.08/0.0315=2.54
0.0055 is the probability
