You have long suspected that the colors are not evenly distributed in a bag of M&M’s. Out of curiosity, you decide to construct a confidence interval for the proportion of orange M&M’s in a bag of peanut M&M’s. Open the dataset ‘MMs_Data.csv’ file in StatCrunch. Treat the dataset as your bag of peanut M&M’s (a simple random sample). Count the number of orange M&M’s and the total number of M&M’s in your bag. Then determine the proportion of your M&M’s that are orange. Number of orange M&M’s: ………………………… Total number of M&M’s: ……………………………. Proportion of orange M&M’s: ……………………..
