Is there a linear relationship between a male's adult height and his father's adult height? Is there is a linear relationship between a male's adult height and the adult height of his male cousin? Suppose that a genealogist investigates these questions. She hypothesizes that there is a linear relationship between a son's height and his father's height. She hypothesizes that there is not a linear relationship between a son's height and the height of his male cousin. The population of interest is families with at least one son and at least one male cousin of the son (or sons). A random sample of 30 families is selected from the target population. The sample data are stored in the FatherSon data set in the DataView tool. Analyze the relationship between a son's height and his father's height by calling up a scatter diagram in the tool. The scatter diagram suggests that there a linear relationship between a son's height and his father's height. Analyze the relationship between a son's height and his cousin's height by calling up a scatter diagram in the tool. The scatter diagram suggests that there a linear relationship between a son's height and his cousin's height. The
