DQ 4: Analysis 1. Are the data for the weight of the girls normally distributed? Explain fully. The weight for the girls is not normally distributed because on the graph, there is no bell shape present for this data set. 2. Are the data for the weight of the boys normally distributed? Explain fully. The weight for the boys is not normally distributed because on the graph, there is no bell shape present within the data set. 3. Calculate the mean and the SD for the girls at birth. Use the Empirical Rule to determine the interval within which 95% of the birth weights fall. 4. Calculate the mean and the SD for the boys at birth. Use the Empirical Rule to determine the interval within which 95% of the birth weights fall. 5. Compare the intervals from 3 and 4. Do they indicate there is a difference in the birth weights of girls and boys? Explain fully
