Data were collected from a group of senior citizens, ages 65 and older, about their age and pet ownership. The results were used to calculate the model ŷ = –0.24x + 18.48, where x represents the age in years and ŷ represents the predicted number of pets owned. If a 25-year-old is predicted to have more than 12 pets, would that be a reasonable use of the model?  This is reasonable because the prediction is based on someone within the original population.  This is not reasonable because the prediction is based on someone outside the original population.  This is reasonable because the model is based on real data.  This is not reasonable because it is impossible to own more than 12 pets.
