Views on Capital Punishment
Use the data given in Exercise. Make the two given tables into one table by combining men for capital punishment into one group, men opposing it into another, women for it into one group, and women opposing it into another.
Show your two-way table. The student who collected the data could have made the results misleading by trying persuasion more often on one gender than on the other, but she did not do this. She used persuasion on 10 of 20 women (50%) and on 15 of 30 men (50%).
a. What percentage of the men support capital punishment? What percentage of the women support it?
b. On the basis of these results, if you were on trial for murder and did not want to suffer capital punishment, would you want men or women on your jury?
Exercise
Views on Capital Punishment In carrying out a study of views on capital punishment, a student asked a question two ways:
1. With persuasion: "My brother has been accused of murder and he is innocent. If he is found guilty, he might suffer capital punishment. Now do you support or oppose capital punishment?"
2. Without persuasion: "Do you support or oppose capital punishment?" Here is a breakdown of her actual data.
a. What percentage of those persuaded against it support capital punishment?
b. What percentage of those not persuaded against it support capital punishment?
c. Compare the percentages in parts a and b. Is this what you expected? Explain.
