Test the null hypothesis that the coefficient associated with gestational age is equal to zero. Now fit a model with length as the outcome and both gestational age and toxemia as predictors. Test the null hypothesis that the coefficient associated with toxemia is equal to zero. As part of your conclusion, include an interpretation of the coefficient associated with toxemia. Do you think the model with both gestational age and toxemia is better than the model with gestational age alone for predicting length?
