Data Set 11 in Appendix B contains weights of 100 randomly selected M&cM plain candies. Those weights have a mean of 0.9147 g and a standard deviation of 0.0369 g. A previous edition of this book used a different sample of 100 M&M plain candies, with a mean and standard deviation of 0.9160 g and 0.0433 g, respectively. Is the discrepancy between the two sample means significant?
