5 (10) Beth ran an experiment to test optimum power and time settings for microwave popcorn. Her goal was to deliver popcorn with fewer than 10% of the kernels left unpopped, on average. She determined that power 9 at 4 minutes was the best combination. To be sure that the method was successful, she popped 8 more bags of popcorn (selected at random) at this setting. All were of high quality, with the percentages of unpopped kernels shown below, 5.1, 6.1, 9.2, 8.1, 4.8, 12.6, 3.6, 92 D Does this provide evidence that she met her goal of an average of fewer than 10% unpopped kernels? Use 0.05 as the P-value cutoff level. Calculate the test statistic T= (Round to three decimal places as needed.)
