Suppose you want to study how effective a hypertension treatment medication is in controlling the blood pressure of participants. You are given a hospital record with the name of 200 patients and want to select 20 patients to participate in your study. You plan to assign 10 participants to the treatment group and 10 participants to the placebo group. (Hint: Random-Number tables.)

1. What steps would you take to select the samples?
2. Using the random digit in the Table of 1000 random digits, randomly select the participants into treatment and placebo groups, without replacement? Indicate the numbers you selected into each group and describe the position in the random-number table where you started your selection.
