(n = 50) (k =8)
Use the standard error to construct an approximate prediction interval for Y using an alpha of 5%. (Round your answer to 3 decimal places.) Prediction interval for Y: yiy^i
Based on the width of this prediction interval, would you say the predictions are good enough to have practical value?
