imagine that you work for a medical research company, and your company developed a new medication to relieve insomnia. A medical experiment is necessary to show that the new medication is effective. 1. The researchers initially sent out surveys to 600 insomnia patients whose addresses were obtained from medical records from ten hospitals. 100 patients were interested. Describe some potential issues with this survey method.

So now you have 100 patients available for the experiment (please see last page with their names, gender, and age) but unfortunately, you have limited budget, and you can only pay for 40 patients. Use your phone or computer to generate random numbers (just Google "random number generator"). Generate 40 random numbers between 1 and 100; if some numbers are repeating, ignore the repetitions and generate more numbers as needed.

2.

a. Generate a Simple Random Sample from the 100 available patients. Write down the 40 generated random numbers from your phone or computer and circle the corresponding patients' names for this sample on the last page. b. Do people numbered 1-40 in the original list of 100 people have the same chance to be selected as the 40 people you got selected? Explain.

3. Describe how you would do a systematic sample choosing 40 patients out of 100. How do you decide where to start counting? How do you decide what to count by? Mark the chosen patients with an X on the last page.
