Last part: Does this provide evidence that Melissa met her goal?A. Yes, there is enough evidence to accept the hypothesis that less than ?7% of the kernels were left unpopped.B. No, there is not enough evidence to accept the hypothesis that less than 7?% of the kernels were left unpopped.C. No, there is not enough evidence to reject the hypothesis that 7?% ?(or more) of the kernels were left unpopped.D. Yes, there is enough evidence to reject the hypothesis that 7?% ?(or more) of the kernels were left unpopped.

Melissa ran an experiment to test optimum power and time settings for microwave popcorn. Her goal was to deliver popcorn with fewer than 7% of the kernels left unpopped, on average. She determined that power 9 at 4 minutes was the best combination. Complete parts a) and b) below. a) She concluded that this popping method achieved the goal of fewer than 7% of the kernels left unpopped. If it really does not work that well, what kind of error did Melissa make? Type l error O Type II error b) To be sure that the method was successful, she popped 8 more bags of popcom (selected at random) at this setting. All were of high quality, with the percentages of unpopped kernels shown below. 13.5, 2.6, 5.3, 2.8, 8.8, 4.4, 25, 6.7 Does this provide evidence that she met her goal of an average of fewer than 7% unpopped kernels? Assume a = 0.05. Choose the correct null and alternative hypotheses. O A. Ho: H#7 OB. Ho: H=7 HA: H=7 HA: H > 7 O C. Ho: H>7 OD. Ho:H
