Question

Figure A shows a scatterplot with the regression line for pulse rates for a large number of students in a college statistics class before and after running in place for two minutes. Figure B shows the residual plot of the data. Figure C shows a QQ plot of the residuals. Is the linear regression model appropriate for these data? Why or why not? Assume the observations are independently measured.
