2. The owner of a Taco shop saw reviews that there was not enough cheese on her tacos. Without identifying herself, she randomly purchased 250
tacos from her own stores and from her competitor. She weighted the
amount of cheese on each taco. Her results are below:
Taco Shop Competitor Total
<15g of cheese 15
11
26
15g< cheese<25g 82
68
150
>25g of cheese 41

250
a) Is there an association between the amount of cheese and where the taco
was purchased?
b) Should the owner of shop adjust the amount of cheese based on what her
competitor is doing?
