2. A medical study of heart surgery investigates the effect of a drug called a beta-blocker on the pulse rate of the patient during surgery. The pulse rate will be measured at a specific point during the operation. The investigators will use 20 patients facing heart surgery as subjects. You have a list of these patients, numbered 1 to 20, in alphabetical order.
a. Describe the design of a completely randomized experiment to test the effect of beta-blockers on pulse rate during surgery. Write a few sentences about how you would implement your design.
b. Use the section from the random digits table below to carry out the randomization required by your design and report the result.

3. Do cell phones turn teen drivers into senior citizens? A study done at the University of Utah says that when young adults drive and talk on cell phones, they drive like senior citizens! You want to collect your own data by surveying the amount of cell phone usage of Lindbergh seniors and the number of accidents that have occurred. Dr. Helms has agreed to pay for the cost of contacting 100 students.
a. Describe your population.
b. Describe a stratified sampling design that you will use to survey the students.
c. Is this an SRS? Why or why not?
4. Is the right hand generally
