Using the weights of only the brown M&Ms listed in Data Set 11 of Appendix B, test the claim that the mean is greater than 0.9085 g, the mean value necessary for the 1498 M&Ms to produce a total of 1361 g as the package indicates. Use a 0.05 significance level. For the brown M&Ms,  = 0.9128 g and s = 0.0395 g. Based on the result, can we conclude that the packages contain more than the claimed weight printed on the label?
Use the traditional approach summarized. Draw a graph showing the test statistic and critical values. In each case, assume that the population has a distribution that is approximately normal and that the sample is randomly selected.
