Following are weights in pounds for random samples of 17 newborn baby boys and baby girls born in Denver in 2011. Box plots indicate that the samples come from populations that are approximately normal. Let m1 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 a=0.05 level and the p-value method with the TI-84 Plus calculator. Boys are 8.3, 7.3, 6.4, 8.4, 8.5, 6.9, 6.3, 7.4, 7.8, 7.5, 6.9, 7.8, 8.6, 7.7, 7.4, 7.7, 8.1. Girls are 7.5, 5.7, 6.6, 6.4, 8.5, 7.2, 6.9, 8.2, 6.5, 6.7, 7.2, 6.3, 5.9, 8.1, 8.2, 6.7, 6.2.
