Orange M&M's: The M&M's web site says that 20% of milk chocolate M&M's are orange. Let's assume this is true and set up a simulation to mimic buying 200 small bags of milk chocolate M&M's. Each bag contains 55 candies. We made this dotplot of the results. The number of orange M&M's was counted and here is a dotplot of the results: $800 0.0 0.1 0.2 0.3 Proportion_Orange An error in the simulation 0.4 Which of the following reasons best explains the variability we see in the proportion of orange M&M's in the bags? The random selection of samples Human error in calculating the proportion of orange M&M's in a bag Poor quality control in the production process 0.5
