Problems 9 10 A regression analysis of the length of a West

Problems 9 - 10. A regression analysis of the length of a Western Hognose snake (in mm) and its age (in days) produced the prediction equation Length = 278 + 0.44. Age. All measurements of the length were performed for ages between 200 and 700 days. 9. Predict the length of a Western Hognose snake after 450 days. A) 410 nun B) 432 mm C) 454 mm D) 476 mm E) 498 mm

Solution

Regression Equation is Length=278 + (0.44)*Age

Now predicting the length of a Western Hognose snake after 450 days is

Length = 278 + (0.44) 450 = 476
