In this R script, we compare the effects of medication for two independent groups on blood pressure. We apply F-test (for normality assumptions) and Levene's test (a more robust method) to test for the homogeneity of variance. If the variances are the same for each group, we use the pooled variance and compare the differences in the means between the two groups. Otherwise, the variances are unequal, and we apply the Welch's t-Test to determine the differences in averages between the two groups.
