A geneticist performs an exploratory data analysis on a sample of several hundred families consisting of a mother, a father, and one or more children. For each family, he computes the average height of the two biological parents and also the average height of their biological children. On a coordinate system he creates a graph by plotting one point for each family, with the axes representing the average height of all children and the average height of all parents.
The horizontal coordinate of the point represents the height of the parents, in inches, and the vertical coordinate of the point..

represents the height of the children. Based on the graph, what can you conclude about the heights of the biologically related parents and their children. This is the link to the graph: http://img14.imageshack.us/img14/2932/mathbfq.jpg Check all that apply. A. The very tallest parents tend not to have the very tallest children. B. Parents of medium height tend to have children of medium height. C. There is no relationship between the height of parents and their children. D. The very shortest parents tend to have the very shortest children. E. Overall, taller parents tend to have taller children.
