Question
Use the following scenario for problem 1 through 10. The importance of Stem Cell
research. There has been considerable debate about legalizing Stem Cell research. In
order to add our 2 cents worth to the debate, I have decided to ask the following
question, “Do you think that Stem Cell research should be legalized in the United
States; YES or NO?” to a sample of 20 people who have at least one parent with
Alzheimer’s disease and to a sample of 30 people who do not have a parent with
Alzheimer’s disease. Here are the results
Stem Cell Research Should be Legalized
YES NO
Parent with Alzheimer’s Disease 18 2
No Parent with Alzheimer’s Disease 10 20
