According to a 2009 Reader's Digest article, people throw away about 9% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 188 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.14?

Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations.
