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 youngest brother? Suppose that a genealogist investigates these questions. He hypothesizes that there is a linear relationship between a son's height and his father's height. He hypothesizes that there is not a linear relationship between a son's height and the height of his youngest brother. The population of interest is families with at least two sons. A random sample of 3:] families is selected from the target populaijon. The sample data are stored in the FatherSon data set in the Data9ie'w tool.

The soatterplot suggests that there a linear relationship between a son's height and his father's height. Analyze the relation ship between a son's height and his brother's height by calling up a soatterplot in the tool. The soatterplot suggests that there a linear relationship between a son's height and his brother's height. Analyze the relationship between a son's height and his father's height by calling up a scatterplot in the tool. The scatterplot suggests that there a linear relation ship between a son's height and his father's height. Analyze the relationship between a son's height and his brother's height by calling up a scatte rplot in the tool. The scatterplot suggests that there a linear relation ship between a son's height and his brother's height. The genealogist is only interested in whether a son's height is linearly related to the height of a male relative. He is not interested in the form of the linear relationship. Therefore. it's not necessary to estimate the linear regression model. The oorrelation coefficient for son's height and his father's height is r = 0.9??0. Test the hypothesis that there is no linear relationship between a son's height and his father's height. The test statistic is t = , and you conclude that there is a linear relationship between the heights. The oorrelation coefficient for son's height and his brother's height is r = 0.3213. Test the hypothesis that there is no linear relationship between a son's height and his brother's height. The test stastic is t = , and you conclude that there is a linear relationship between the heights
