Bivariate Data, SM-Bank 007 MC

Dr Chris measures the weights (in grams) and lengths (in cm) of 12 baby pythons.

The results were recorded and plotted in the scatterplot below. The line of best fit that enables the weight of the pythons to be predicted from their length has also been plotted.
 

The line of best fit predicts that the weight, in grams, of a python of length 30 cm would be closest to

  1. `240`
  2. `252`
