Using the methods we have studied, both graphical and formal, compare the glucose test results for pregnant and non-pregnant women. It would be of interest to study the difference between the means and the ratio of the variances or standard deviations, as well as qualitative features such as the shape of the distributions. Use the data from the first glucose test for each group (that is, the first column of each data frame). These are independent samples.
In each case state your conclusions, and the evidence used to reach your conclusions.
