Body measurements, Part III. Exercise 7.15 introduces data on shoulder girth and height of a group of individuals. The mean shoulder girth is 107.20 cm with a standard deviation of 10.37 cm. The mean height is 171.14 cm with a standard deviation of 9.41 cm. The correlation between height and shoulder girth is 0.67. (a) Write the equation of the regression line for predicting height. (b) Interpret the slope and the intercept in this context. (c) calculate R2 of the regression line for predicting height from shoulder girth, and interpret it in the context of the application. (d) A randomly selected student from your class has a shoulder girth of 100 cm. Predict the height of this student using the model. (e) The student from part (dy is 160 cm tall. Calculate the residual, and explain what this residual means. (f)A one year old has a shoulder girth of 56 cm. Would it be appropriate to use this linear model to predict the height of this child?
