Document Summary
Linear regression with one regressor (cid:132) solutions to exercises (a) the predicted average test score is. 520 4 5 82 22 392 36 (b) the predicted change in the classroom average test score is. In equation (4. 8), we know the sample average of the test scores across. 520 4 5 82 21 4 395 85 (d) use the formula for the standard error of the regression (ser) in equation (4. 19) to get the sum of squared residuals: 2r in equation (4. 16) to get the total sum of squares: 11 5: the sample size n = Weight (2 15) 99 41 (0 31) 3 94. 70, 65, and 74 inches into the equation, the predicted weights are 176. 39, Weight (b) 3 94 (c) we have the following relations: 1. 2 54 in equation in the centimeter-kilogram space is. 2r is unit free, so it remains at kg.
