7.20 Body measurements, Part III. Exercise 7.13 introduces dataon shoulder girth and height of a group of individuals. The meanshoulder girth is 107.30 cm with a standard deviation of 10.34 cm.The mean height is 171.14 cm with a standard deviation of 9.41 cm.The correlation between height and shoulder girth is 0.69. 1. (a)Write the equation of the regression line for predicting height. 2.(b) Interpret the slope and the intercept in this context. 3. (c)Calculate R2 of the regression line for predicting height fromshoulder girth, and interpret it in the context of the application.4. (d) A randomly selected student from your class has a shouldergirth of 100 cm. Predict the height of this student using themodel. 5. (e) The student from part (d) is 160 cm tall. Calculatethe residual, and explain what this residual means. 6. (f) A oneyear old has a shoulder girth of 56 cm. Would it be appropriate touse this linear model to predict the height of this child? *answersto 3 decimal points*!!!
