Chapter 12, Problem 25E(choose chapter or problem)
Recall the regression of percent of body fat on height and waist from Exercise 12-1. The simple regression model of percent of body fat on height alone shows the following:
\(\begin{array}{l} \text { Estimated Std. Error t value Pr }(>|t|) \\ \text { (Intercept) } & 25.58078 & 14.15400 & 1.807 & 0.0719 \\ \text { Height } & -0.09316 & 0.20119 & -0.463 & 0.6438 \end{array}\)
Test whether the coefficient of height is statistically significant.Looking at the model with both waist and height in the model, test whether the coefficient of height is significant in this model.Explain the discrepancy in your two answers.
