The relationship of horsepower of motorcycles to miles per gallon is represented by the following scatter plot:
Scatter plot with horsepower on the x axis and observed MPG on the y axis. The points plotted are 62 and 32, 63 and 31, 66 and 30, 71 and 30, 75 and 29, 81 and 27, 91 and 24, 94 and 25, 97 and 21, 99 and 20, 104 and 21, 114 and 18, 115 and 19, 120 and 17.
Jorge created the following residual plot:
Residual plot with x axis labeled horsepower and y axis labeled residuals. The points plotted are 62 and 0.44, 63 and negative 0.3, 66 and negative 0.52, 71 and 0.78, 75 and 0.82, 81 and 0.38, 91 and negative 0.02, 94 and 1.76, 97 and negative 1.46, 99 and negative 1.94, 104 and 0.36, 114 and negative 0.04, 115 and 1.22, 120 and 0.52.
Does his residual plot make sense based on the scatter plot? Explain.
The random residual plot makes sense because the scatter plot appears to have a linear relationship.
The random residual plot makes sense because the scatter plot appears to have a negative relationship.
The random residual plot does not make sense because it should have a linear relationship like the scatter plot.
The random residual plot does not make sense because it should have a nonlinear curve, as the scatter plot is negative.
