Chapter 1, Problem 64CRE

Writing: Strokes People who have had strokes are often put on “blood thinners” such as aspirin or Coumadin to help prevent a second stroke. Describe the design of a controlled experiment to determine whether aspirin or Coumadin works better in preventing second strokes. Assume you have 300 people who have had a first stroke to work with. Include all the features of a good experiment. Also decide how the results would be determined.
