Pregnancy women are enrolled and randomly assigned to receive the experiment drug, the standard drug or placebo. Women are followed through delivery and classified as delivering preterm (<37weeks) 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? Apply the test at a 5% level of significance.
