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 | 21 | Red | 22 | Yellow | 22 |
Orange | 12 | Green | 17 | Blue | 14 |
Using the 2 goodness of fit test ( = 0.05) to determine if the proportion of M&Ms is what is claimed. Select the [test statistic, p-value, Decision to Reject (RH0) or Failure to Reject (FRH0)].
a) [2 = 10.923, p-value = 0.053, RH0]
b) [2 = 5.461, p-value = 0.947, RH0]
c) [2 = 10.923, p-value = 0.053, FRH0]
d) [2 = 10.923, p-value = 0.026, RH0]
e) [2 = 5.461, p-value = 0.947, FRH0]
f) None of the above
