Use the same Appendix B data sets as Exercises 29-32 in Section 10-1. In each case, find the regression equation, letting the first variable be the predictor (x) variable. Find the indicated predicted values following the prediction procedure summarized in Figure 10-5 on page 493.

Repeat Exercise 13 using all of the paired Internet > Nobel data listed in Data Set 16 "Nobel Laureates and Chocolate" in Appendix B?

Figure 10-5

Repeat Exercise 13:
Find the best predicted Nobel Laureate rate for Japan, which has 79.1 Internet users per 100 people. How does it compare to Japan's Nobel Laureate rate of 1.5 per 10 million people?

Strategy for Predicting Values of y Is the regression equation a good model? The regression line graphed in the scatterplot shows that the line fits the points well. r indicates that there is a linear correlation. The prediction is not much beyond the scope of the available sample data. Yes. The regression No. The regression equation is not a good model. equation is a good model. Substitute the given v into the regression equation alue of X Regardless of the value of x, the best predicted value of y is the value of y (the mean of the y values) 56.8 3.3 67.6 1.7 Internet Users 79.5 79.6 9.0 77.9 38.3 Nobel Laureates 5.5 10.8 0.1
