33. Popcorn. Yvon Hopps ran an experiment to test optimumpower and time settings for microwave popcorn.His goal was to find a combination of power and time thatwould deliver high-quality popcorn with less than 10% of the kernels left unpopped, on average. After experimentingwith several bags, he determined that power 9 at4 minutes was the best combination.a) He concluded that this popping method achieved the10% goal. If it really does not work that well, whatkind of error did Hopps make?b) To be sure that the method was successful, he popped8 more bags of popcorn (selected at random) at thissetting. All were of high quality, with the followingpercentages of uncooked popcorn: 7, 13.2, 10, 6, 7.8,2.8, 2.2, 5.2. Does this provide evidence that he met hisgoal of an average of no more than 10% uncooked kernels?Explain.
