M&M Mars Company has varied the mix of colors for M&M'S Plain Chocolate Candies over the years. These changes in color blends are the result of consumer preference tests. Most recently, the color distribution is reported to be 13% brown, 14% yellow, 13% red, 20% orange, 24% blue, and 16% green. You open up a 14 ounce bag of M&M's and find 61 brown, 61 yellow, 49 red, 77 orange, 143 blue, and 84 green. Use a goodness of fit test to examine how well this bag fits the percents stated by the M&M Mars Company.
