The text intentionally does not give answers to activities partly because some of the activities can have more than one answer and partly because the text uses the discovery method of teaching statistics. With the discovery method students are guided in discovering statistical rules and formulas for themselves. It would defeat the purpose to have students working the problems backward from the answers. I have attached some possible answers for your convenience in checking your work. For many of the problems there is more than one possible answer. You will learn best if you try to do the activities on your own first before looking at my answers. If you find that you need to look at the answers frequently then I suggest that you either redo the activities without looking at the answers or do some additional activities for which I have not provided answers.
