The relationship of horsepower of speedboats to weight is represented by the following scatterplot: scatterplot with horsepower on the x axis and weight on the y axis. the points plotted are 62 and 1600, 63 and 2199, 66 and 1797, 71 and 2507, 75 and 1980, 81 and 2404, 91 and 2606, 94 and 2580, 97 and 2434, 99 and 2611, 104 and 2812, 114 and 3382, 115 and 3248, 120 and 2922. amy created the following residual plot: residual plot with x axis labeled horsepower and y axis labeled residuals. the points plotted are 62 and negative 2, 63 and negative 1.75, 66 and negative 1.25, 71 and negative 0.75, 75 and negative 0.5, 81 and 0, 91 and 0.5, 94 and 0.25, 97 and negative 0.5, 99 and negative 1, 104 and negative 1.25, 114 and negative 1.5, 115 and negative 2, 120 and negative 1.9. does her residual plot make sense based on the scatterplot? explain.
a. the nonlinear, u-shaped residual plot makes sense because the scatterplot appears to have a positive relationship.
b. the nonlinear, u-shaped residual plot makes sense because the scatterplot appears to have a linear relationship.
c. the nonlinear, u-shaped residual plot does not make sense because it should have a linear relationship like the scatterplot.
d. the nonlinear, u-shaped residual plot does not make sense because it should have a random pattern as the scatterplot appears to be linear.
e. unable to determine the residual plot because the lsrl is not given.
