Given the information in Exercise 15.13, determine and interpret the 90% confidence and prediction intervals associated with burned acreage in Florida when the January–May rainfall in the state is 20 inches.
In exercise
The Florida ecosystem is heavily reliant on wet and dry seasons, and is particularly dependent on the winter and spring rainfall that helps reduce damage due to wildfires. Data file XR15013 lists the number of acres burned and the number of inches of rainfall during January–May for 1988–2000. Given these data, determine the least-squares equation for predicting acreage burned during the January–May period as a function of rainfall during that period, then interpret its slope.
