Examine the scatterplot below, used to predict stopping distance based off motorists’ speed.
Which feature does this scatterplot show that might make one leery of using this as a model for prediction?
The correlation is weak to moderate.
More pieces of data should be used to make predictions more reliable.
As speed increases, there seems to be more variability in stopping distance.
The stopping distance seems to level off as speed increases.
There is no data in the speed range past $40$ miles per hour.
