1. The body weights of 578 chicks were measured at birth and every second day thereafter until day 20. They were also measured on day 21. Chicks were split into four groups, being fed four different protein diets. We fit a regression model to predict the weight of chicks based on the number of days since birth and on the type of diet, including the interaction between these two predictors. ## Call: "# 1m(formula = weight ~ Time .
