According to a 2009 Reader's Digest article, people throw away approximately 11% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 139 grocery shoppers to investigate their behavior. What is the probability that the sample proportion exceeds 0.08? Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations. Answer =  (Enter your answer as a number accurate to 4 decimal places.)

State the mean and variance of the sampling distribution of the mean?

The provost believes that 27 % of Cal Poly students are pleased with the courses. A group was asked in front of the library if they were content with the various courses offered. Out of the 113 students asked, 31 students were content with the various courses offered
