Question:

Suppose that a simple linear regression of miles per gallon (Y) on car weight (X) has been performed with n = 32 observations. Suppose that the least-squares estimates are Other useful statistics are = 30.91, and
a. Suppose that we want to predict miles per gallon Y for a new observation with weight X = 24. What would be our prediction?
b. For the prediction in part (a), find a 95 percent prediction interval for the unobserved Y value.
