A statistics professor bought a new car for $35,000. For the next 5 years, she used several automotive web pages to estimate the value of the car. She then found the least‑squares regression line for the data to be ^ y = 35035.71 − 4142.86 x. The correlation coefficient was − 0.99 . Would it be accurate to use this equation to predict the value of the car after 10 years?
a) No, because the value of cars is unpredictable over time.
b) Yes, because the correlation is very strong.
c) No, because that would be extrapolation.
