Quarters have weights that are uniformly distributed between 5516 and 5794 mg, with a standard deviation of 9.8 mg. StatCrunch a) What is the probability that the mean of a sample of 339 different quarters falls between 5655 and 5788 mg.? % (round answer to a whole number percentage) Does the Central Limit Theorem apply to part a? Yes - because we are looking at the mean of the sample of 339 coins which is > 30. No - because the population is NOT normally distributed. b) A vending machine is configured to only accept quarters with weights between 5553 and 5788 mg. Customers insert 339 different quarters into this machine (one at a time). Does the Central Limit Theorem apply to part b)? No - because 1 coin at a time is inserted Yes - because 339 coins are all inserted into the machine at once which is > 30. % of the quarters will be accepted and % of them will be rejected. (round answers to a whole number percentage) What is the expected number of rejected quarters out of 339? (round to a whole number).
