Refer to Data Set 8 in Appendix B and use
Refer to Data Set 8 in Appendix B and use the times (seconds) that animated Disney movies showed the use of tobacco and the times that they showed the use of alcohol. 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?
Use the indicated Data Sets from Appendix B. Assume that the paired sample data are simple random samples and the differences have a distribution that is approximately normal.
