Mars Inc. claims that they produce M&Ms with the following distributions:
Brown | 20% | Red | 25% | Yellow | 25% |
Orange | 5% | Green | 15% | Blue | 10% |
A bag of M&Ms was randomly selected from the grocery store shelf, and the color counts were:
Brown | 22 | Red | 21 | Yellow | 19 |

a)[2= 12.583, p-value = 0.028, RH0]
b)[2= 6.292, p-value = 0.972, RH0]
c)[2= 12.583, p-value = 0.028, FRH0]
d)[2= 6.292, p-value = 0.972, FRH0]
e)[2= 12.583, p-value = 0.014, RH0]
