Dаtа аnd R оutput оn the incidence оf respiratory disease in infants by sex and feeding method are below. The reference levels for the categorical predictor variables sex and food are Boy and Bottle Only, respectively. The output gives a logistic regression model for the probability of respiratory disease: Use the model to predict the probability that a baby girl who only bottle feeds will contract a respiratory disease.
