9.[8] In a study of balloon angioplasty, patients with coronary artery disease were randomly assigned to one of four treatment groups: placebo, probucol (an experimental drug), multivitamins (a combination of beta carotene, vitamin E, and vitamin C), or probucol combined with multivitamins. Balloon angioplasty was performed on each of the patients. Later, \"minimal luminal diameter\" (a measurement of how well the angioplasty did in dilating the artery) was recorded for each of the patients. Summary statistics are given in the following table. a) Complete the ANOVA Table above by calculating the values for the four highlighted cells. b) Perform an ANOVA F test with a null hypothesis stating that the means for the four treatment groups are equal. Use a = 0.01. Include the following in your analysis: Ha, Ha, the value of the test statistic (F), the bracketed P-value, your decision regarding H0, and your conclusion stated in the context of the problem. ed States)
