# A biologist is interested in the relationship between feeding time (hr) and body weight (kg) in 
# the males of a mammalian species. The data he recorded are shown in the table. The objectives are:
# Construct an equation relating TIME to BODYWT.
# Understand the model selection criteria.
# Estimate mean TIME for a given BODYWT with 95% CLM.
