According to a 2009 Reader's Digest article, people throw away about 10% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 185 grocery shoppers to investigate
their behavior. What is the probability that the sample proportion does not exceed 0.15?
Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach
and calculations.
Answer = 1
(Enter your answer as a number accurate to 4 decimal places.)
