Testing Hypotheses. In Exercises 924, assume that a simple random sample has been selected and test the given claim. Unless specified by your instructor, use either the Pvalue method or the critical value method for testing hypotheses. Identify the null and alternative hypotheses, test statistic, Pvalue (or range of Pvalues), critical value(s), and state the final conclusion that addresses the original claim. M&M Weights A simple random sample of the weights of 19 green M&Ms has a mean of 0.8635 g and a standard deviation of 0.0570 g (as in DataSet 20 in Appendix B). Use a 0.05 significance level to test the claim that the mean weight of all green M&Ms is equal to 0.8535 g, which is the meanweight required so that M&Ms have the weight printed on the package label. Do green M&Ms appear to have weights consistent with the packagelabel?
