Mars Inc. claims that they produce M&Ms with the following distributions:

Brown	30%	Red	20%	Yellow	20%
Orange	10%	Green	10%	Blue	10%

A bag of M&Ms was randomly selected from the grocery store shelf, and the color counts were:

Brown	22	Red	24	Yellow	19
Orange	14	Green	15	Blue	15

Using the χ² goodness of fit test to determine if the proportion of M&Ms is what is claimed, what is the test statistic?

a) χ² = 8.049

b) χ² = 16.098

c) χ² = 1.960

d) χ² = 7.249
