Question: The output shown was obtained from Minitab. (a) The least-squares regression equation is = 1.3962x + 12.396. What is the predicted value of y

The output shown was obtained from Minitab.

The regression equation is y = 12.4 + 1.40 x Predictor Constant Coef 12.396 1.3962 StDev т 0.000 0.000 8.97 1.381 11.21

(a) The least-squares regression equation is Å· = 1.3962x + 12.396. What is the predicted value of y at x = 10? (b) What is the mean of y at x = 10?
(c) The standard error, se, is 2.167. What is an estimate of the standard deviation of y at x = 10?
(d) If the requirements for inference on the least-squares regression model are satisfied, what is the distribution of y at x = 10?

The regression equation is y = 12.4 + 1.40 x Predictor Constant Coef 12.396 1.3962 StDev 0.000 0.000 8.97 1.381 11.21 0.1245 S = 2.167 = 91.3% = 90.6% R-Sq (adj) R-Sq 90.6%
