Suppose we are asked to construct a list of treatment assignments for patients entering a study comparing different treatments for duodenal ulcer.

Anticipating that 20 patients will be entered in the study and two treatments will be used, construct a list of random-treatment assignments starting in the 28th row of the random-number table (Table 4 in the Appendix).

Expert Solution & Answer

To determine

Find the list of random-treatment assignments using random-number table.

Explanation of Solution

Consider the treatment A and treatment B.

If the random digit is 0 to 4, then the patients are assigned to treatment A.

If the random digit is 5 to 9, then the patients are assigned to treatment B.

The treatment assignments by using 28^th row in the random number table are given below:

Patient number	Random digit	Treatment assignment
1	6	B
2	9	B
3	6	B
4	4	A
5	4	A
