According to a 2009 Reader's Digest article, people throw away about 12% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 119 grocery shoppers to investigate their behavior. What is the probability that the sample proportion does not exceed 0.18?

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
