Yvon Hopps ran an experiment to determine the optimum power and time settings for microwave popcorn. His goal was to find a combination of power and time that would deliver high-quality popcorn with less than 9% of the kernels left un-popped, on average. After experimenting with several bags, he determined that power 9 at 4 minutes was the best combination. To be sure that the method was successful, he popped 8 more bags of popcorn (selected at random) at this setting. All were of high quality, with the following percentages of uncooked popcorn: 8.4, 11.4, 8.7, 8.3, 4.6, 2.4, 3.2, 5.6. Does the 95% confidence interval suggest that he met his goal of an average of no more than 9% uncooked kernels? Explain. The 95% confidence interval for the true mean percentage of unpopped kernels is (%,%). (Round to two decimal places as needed. Use ascending order.)
