The M&Ms milk chocolate color distribution is the following: 25% blue, 35% orange, 23% red, and 17% brown. In a bag, I found 160 blue M&Ms, 224 orange ones, 169 red ones and 99 brown ones.I am wondering whether my bag of M&Ms is representative of the manufacturer's claim. Calculate the absolute value of the test statistic. number (rtol=0.01, atol=D0.0001) Calculate the absolute value of the test statistic that would correspond to a = 0.05. number (rtol=0.01, atol=D0.0001) Using a level of significance of a = 0.05, do the M&Ms in the bag match the required color distribution?
