11-104.

The owner of Taco Shack saw reviews online complaining that there was not enough cheese on his tacos. Without identifying himself, he randomly purchased $251$ tacos from his own stores and from his competitor. He weighed the amount of cheese on each taco. His results are below:

$\boldsymbol{>25}$ grams cheese

$41$

$33$

TOTAL

Is there an association between the amount of cheese and where a taco was purchased? Should the owner of Taco Shack adjust the amount of cheese based on what his competitor is doing?
