Homework: pg. 276 #5, 6 5.) A. The relationship is strong, negative, and curved. The ratios are all 0.717. Since the ratios are all the same, the exponential growth model is appropriate. Yes. The scatterplot shows that the transformation achieves linearity. ln (light)=6.7891-0.3330(depth). The intercept 6.7891 provides an estimate for the average value of the natural log of the light intensity at the surface of the lake. The slope, -0.3330 indicates that the natural log of the light intensity decreases by 0.3330 for each one meter increase in depth. The plot shows that the linear model on the transformed data is appropriate. The equation is: The predicted light intensity is 0.5846, very close to the observed light intensity.

Homework: pg. 276 #5, 6 6.) A. The model would be: 10-1094.51 would be zero so all predicted values would be zero. F. The ratios are 3.5890, 4.0090, and 3.1156 The residual plot shows no clear pattern so the transformed linear model is appropriate. C. H. I. The predicted number would be 10,722,597.42 acres Yes, this is correct.
