This is part of a multi-part question using the same data: M&M/MARS, makers of M&M Chocolate Candies, conducted a national poll in which more than 1 million people indicated their preference for a new color. The tally of this poll resulted in the replacement of tan-colored M&Ms with a new blue color. In the brochure "Colors," made available by M&M/MARS Consumer Affairs, the distribution of colors for the plain candies is as follows: Brown: 30% Yellow: 20% Red: 20% Orange: 10% Green: 10% Blue: 10% In a follow-up study, samples of 1-pound bags were used to determine whether the reported percentages were indeed valid. The following results were obtained for one sample of 500 plain candies: Observed Color Frequency Brown 175 Yellow 135 Red 80 Orange 40 Green 40 Blue 30 Use a = 0.05 and determine whether these data support the percentages reported by the company.
