A researcher models the relationship between hours of sleep (x) and reaction time in milliseconds (y) using the regression line ŷ = 320 − 48x. (a) Interpret the slope in context: what does it mean for each additional hour of sleep? (b) Interpret the y-intercept in context. (c) Is the y-intercept meaningful in this situation? Explain why or why not.
Answer:
