Will using name-brand microwave popcorn result in a greater
percentage of popped kernels than store- brand microwave popcorn?
To find out, Briana and Maggie randomly selected 10 bags of name-
brand microwave popcorn and 10 bags of store-brand microwave
popcorn. The chosen bags were arranged in random order. Then each
bag was popped for 3.5 minutes, and the percentage of popped kernels
was calculated. The data are displayed in the table.
Name brand 95 88 84 94 81 90 97 93 91 86
Store brand 91 89 82 82 77 78 84 86 86 90
1. make parallel boxplots of the data. write a few sentences comparing the distributions of the percent of popped karnels in the 2 samples
2. do the data provide convincing evidence at the 0.05 significance level that using name-brand microwive popcorn will result in a greater mean percentage of popped karnels?
