scatterplot and residual plot

 

Age and height A random sample of 195 students was selected from the United Kingdom using the CensusAtSchool data selector. The age (in years) x and height (in centimeters) y was recorded for each of the students. A regression analysis was performed using these data. The scatterplot and residual plot are shown below. The equation of the least-squares regression line is  = 106.1 + 4.21x. Also, s = 8.61 and r2 = 0.274.

(a) Calculate and interpret the residual for the student who was 141 cm tall at age 10.

(b) Is a linear model appropriate for these data? Explain.

(c) Interpret the value of s.

(d) Interpret the value of r2.
