We have been told that 45% of all Reese's Pieces are orange, whereas 27.5% are brown and 27.5% are yellow. To determine this hypothesis, some students counted the number of candies of each color in bag of 500 Reese's Pieces. They found 198 orange candies, 155 brown candies, and 147 yellow candies. Carry out the appropriate test by stating the hypotheses, computing the test statistic and p-value, and indicating what decision you would make (in context) using the ? = .05 significance level.
