1. Interpreting Linear Models You fit the following linear model on a dataset of mammal species. Each row includes lifespan (in years), weight (in pounds), and diet (carnivore, omnivore, or herbivore). lifespan = 11.5 +2.0 weight +1.5. carnivore-1.2. omnivore 1.1 Interpret an Indicator pt. 1 (1 point) According to this model, if carnivore A weighs 5 pounds more than carnivore B, what is the difference in predicted lifespans? 1.2 Interpret an Indicator pt. 2 (1 point) According to this model, if an herbivore and a carnivore weigh the same, what is the absolute value of the difference in predicted lifespans? 1.3, thru 1.6 Reframe the regression (4 points) You decide to change the regression to the following: lifespan = Bo + B?-weight + B? carnivore + 33. herbivore What would the resulting coefficients be? (hint: for any mammal you can think of, the predicted lifespans should be the same as the original model) Coefficient Value Bo B? B? B3
