Question

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.

Explanation:

The model was developed using data from senior citizens aged 65 and older. Predicting for a 25 - year - old is extrapolating outside the original population range for which the model was created. Predictions are most reliable within the range of data used to build the model.

Answer:

This is not reasonable because the prediction is based on someone outside the original population.
