A regression model for predicting reaction time r r\,r milliseconds from sleep s s\,s hours is
r=310−12sr=310-12sr=310−12s.
Estimate the reaction time when s=8s=8s=8.
An observed reaction time at s=8s=8s=8 is 226 ms. Calculate and interpret the residual.
Explain why the model should not be used for s=16s=16s=16.
