Problem 1

13.4 Testing Categorical Probabilities: One-Way Table

M&M candies’ web site claims each package of Milk Chocolate M&M’s should contain 24% blue, 14% brown, 16% green, 20% orange, 13% red, and 14% yellow M&M’s. Use a 1% significance level and the data (that was actually observed by a researcher named Josh Madison) to determine if M&M’s really fill their bags of candy with these proportions:
Blue       Brown      Green       Orange      Red      Yellow
 481          371          483             544          372         369
