Assignment:
Assume that the paired sample data are simple random samples and that the differences have a distribution that is approximately normal.
Tobacco and Alcohol in Children's Movies Listed below are times (seconds) that animated Disney movies showed the use of tobacco and alcohol. (See Data Set 7 in Appendix B.) Use a 0.05 significance level to test the claim that the mean of the differences is greater than 0 sec, so that more time is devoted to showing tobacco than alcohol. For animated children's movies, how much time should be spent showing the use of tobacco and alcohol?
