  • Story:

    Yvon Hopps ran an experiment to determine 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 10% of the kernels left unpopped,
    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. The data report the percentages of uncooked popcorn.
