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
33
74
Total
138
112
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?

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
