Following are weights in pounds for random samples of 16 newborn baby boys and baby girls. Box plots indicate that the samples come from populations that are approximately normal. Let μ1 denote the mean weight of boys. Can you conclude that the mean weight of boys is greater than the mean weight of girls? Use the =α0.10
