1. A researcher would like to compare the observed newborn weights (DBWT), measured in pounds, for the following three groups: (1) newborns whose mothers developed gestational diabetes but did not have pre-pregnancy hypertension; (2) newborns whose mothers developed gestational diabetes and had pre-pregnancy hypertension; and (3) newborns whose mothers did not have/develop any of the following: gestational diabetes, gestational hypertension, pre-pregnancy diabetes, and pre-pregnancy hypertension. Report the means and standard deviations of the newborn weights for these three groups in a single SAS table, and test whether the means of the first two groups, (1) and (2) above, are different from each other (you can assume normality for the purpose of this test). Finally interpret the results of this test
