      1. A popcorn, Inc. needs to determine the optimum power   and time settings for their new licorice-flavored microwave pop-corn. They   want to find a combination of power and time that delivers high-quality   popcorn with less than 10% of the kernels left unpopped, on average-a value   that their market research says is demanded by their customers. their   research department experiments with several settings and determines that   power 9 at 4 minutes is optimum. Their test confirm that this seting meets   the less than 10% requerment. They change the instructions on the box and   promote a new money back guarantee of less than 10% unpopped kernels.   a)   If, in fact the setting results in more than 10% kernels unpopped, what kind   of error have they made       b)   To reduce the rick of making an error, the president tells them to test 8   more bags of popcorn(selected at random) at the specified setting. They find   the following percentage of unpopped kernels: 7, 13.2, 10, 6, 7.8, 2.8, 2.2,   5.2. Does this provide evidence that the settings meets their goal of less   than 10% unpopped? Explain
