Assignment

Lets find a response to each of the problems listed in the textbook for the Gastroenterologycase (problems 6.1 - 6.4).

Gastroenterology

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

6.1 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).
6.2 Count the number of people assigned to each treatment group. How does this number compare with the expected number in each group?
6.3 Suppose we change our minds and decide to enroll

40 patients and use four treatment groups. Use a computer program (such as MINITAB or Excel) to construct the list of random-treatment assignments referred to in Problem 6.1.

6.4 Answer Problem 6.2 for the list of treatment assignments derived in Problem 6.3.
