Using SAS to solve question A and B also provide SAS code. In a study let us consider that four different procedures (A, B, C, and D) are applied to randomly selected Type 2 diabetic subjects to find whether there is difference in the mean performance in controlling their pre-prandial blood glucose level (mmol/l). Procedure A B C D 7.4 8.2 7.5 8.1 5.8 7.2 6.8 7.6 6.2 7.0 7.1 8.4 7.5 8.9 9.3 9.6 7.8 6.4 8.1 9.3 9.2 8.6 11.4 12.8 A. Analyze the data and summarize the results in an analysis of variance table B. Is there evidence in support of variation in preprandial blood glucose level? Perform an appropriate test and comment
