A clinical trial is run to investigate the effectiveness of an experimental drug in reducing high blood pressure in women to a drug considered standard care and to placebo. Women are enrolled and randomly assigned to receive either the experimental drug, the standard drug or placebo. Women are followed through for (< 37 weeks) or not. The data are shown below. Is there a statistically significant difference in the proportions of women having high blood pressure among the three treatment groups? Run the test at a 5% level of significance. Appropriate test?
