(4 pts) Please read the following experiment and answer the questions below.
Mr. Bailey decides to do an experiment to see if different types of popcorn pop faster in the
microwave. The TV commercials say that Popalicious is the fastest popping popcorn in the
world. Mr. Bailey's hypothesis was, "If I pop Jiffy Pop, Popalicious, and Pop-Tastic popcorn in a
microwave, then the Popalicious will pop faster because the commercial says so." He takes
Jiffy Pop, Popalicious, and Pop-Tastic and places them each in the microwave for 2 minutes.
After two minutes is up, he counts the number of POPPED kernels in the bag. After three trials,
Jiffy Pop had an average of 256 popped kernels, Popalicious had an average of 341 popped
kernels, and Pop-Tastic had an average of 357 popped kernels.
