Problem 13BSC

Regression and Predictions. Exercises use the same data sets as Exercises in Section 10-2. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted value by following the prediction procedure summarized in Figure.

Figure Lemons and Car Crashes Find the best predicted crash fatality rate for a year in which there are 500 metric tons of lemon imports.

 Lemon Imports 230 265 358 480 530 Crash Fatality Rate 15.9 15.7 15.4 15.3 14.9
Step-by-Step Solution:
Step 1 of 3

Problem 13BSC

Step1 of 3:

We have  Exercises use the same data sets as Exercises in Section 10-2. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Lemon Imports 230 265 358 480 530 Crash Fatality Rate 15.9 15.7 15.4 15.3 14.9

Step2 of 3:

We need to Find the indicated predicted value by following the prediction procedure summarized in Figure and  Find the best predicted crash fatality rate for a year in which there are 500 metric tons of lemon imports.

Step3 of 3:

Consider,

 Lemon Imports(x) Crash Fatality Rate(y) xy  230 15.9 3657 52900 252.81 265 15.7 4160.5 70225 246.49 358 15.4 5513.2 128164 237.16 480 15.3 7344 230400 234.09 530 14.9 7897 280900 222.01 1863 77.2 28571.7 = 762589 1192.56
