QUESTION 13
A clinical trial is run to investigate the effectiveness of an experimental drug in reducing preterm delivery to a drug considered
standard care and to placebo. Pregnant women are enrolled and randomly assigned to receive either the experimental drug, the
standard drug or placebo. Women are followed through delivery and classified as delivering preterm (< 37 weeks) or not. The data are
shown below. Is there a statistically significant difference in
the proportions of women delivering preterm among the three treatment
groups? Run the test at a 5% level of significance. Give each of the following to receive full credit: 1) the appropriate null
and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your
conclusion including a comparison to alpha or the critical value. You MUST show your work to receive full credit. Partial credit is
