A clinical trial is conducted to determine the effectiveness of drug A in preventing low birthweight deliveries. In the trial, 30 pregnant women are to be studied, 15 assigned to a treatment group that will receive drug A and 15 assigned to a control group that will receive a placebo. The birthweights (in pounds) corresponding to the babies born to the mother's in the trial are presented below: Treatment Group 6.9 7.6 7.3 7.6 6.8 7.2 8.0 5.5 00 7.3 8.2 6.9 6.8 5.7 8.6 Control Group 6.4 6.7 5.4 8.2 5.3 6.6 5.8 5.7 6.2 7.1 7.0 6.9 5.6 4.2 6.8 Use Stata to assess whether or not drug A is effective in preventing low birthweight deliveries, assuming unequal variances. Construct you null and alternative to test whether the weights for the Treatment Group are greater than the weights for the Control Group. Conduct your test at the alpha = 0.03 level.
