A linear model is used to predict the number of hours of sleep () a person gets based on the number of hours they spent on a screen () before bed. The model was developed using data for values between 1 and 6 hours.
Which of the following statements is the best interpretation of the model or its limitations?
For every additional hour spent on a screen, a person is predicted to sleep 1.5 hours more.
The model predicts that a person who spends 0 hours on a screen will sleep 25 hours, which is likely unrealistic.
The model is reliable for predicting sleep for someone who spends 8 hours on a screen before bed.
This model proves that screen time is the sole cause of sleep reduction.
