A biologist collected data on a sample of 20 porcupines. She wants to be able to predict the body mass of a porcupine (in grams) based on the length of the porcupine (in cm) .
Her least squares regression equation is
where M is the mass.
-A scatterplot of the biologist's data, with the least squares regression line, is provided. There is a clear outlier in the lower left corner of the plot. How would removing this point from the dataset most likely affect the correlation between body length (cm) and body mass (g) ?
A) It would make the correlation stronger.
B) It would make the correlation weaker.
C) It would have no impact on the correlation between body length and body mass.
