Project 2 Directions: Show all work, neatly written. Show all 5 steps in the testing process for the hypothesis tests. (Problems 1 and 2 are worth 50 points each.) 1. According to the M&M's website, the distribution of the colors of Milk Chocolate M&M's should be 24% blue. 14% brown, 16% green, 20% orange, 13% red, and 14% yellow. In a random sample of milk chocolate M&M's, the total number of M&M's was 992. Out of that number, the total number of blue M&M's was 225. a. Find the sample proportion of milk chocolate M&M's that are blue. b. Construct a 99% confidence interval for the proportion of blue M&M's in the milk chocolate variety. Show the calculation of the margin of error and the interval endpoints. Show the confidence interval that you obtain. c. Do your results agree with the website's claim, i.e. does your confidence interval contain the proportion stated by the M&M company of 24% blue? d. Carry out a hypothesis test to determine whether the proportion of blue M&M's is different from the value stated on the website. Show the hypotheses, the check of necessary conditions, the test statistic, and the p-value, with all supporting work. State whether or not the null is rejected. State a final conclusion, in context. Use a level of significance of 0.01
