- An experiment was undertaken to investigate the amount of drug present in the liver of a rat. Nineteen rats were randomly selected, weighed, placed under a light anesthetic, and given an oral dose of the drug. It was believed that large livers would absorb more of a given dose than a small liver, so the actual dose given was approximately determined as 40 mg of the drug per kilogram of body weight. After a fixed length of time, each rat was sacrificed, the percent dose in the liver was determined
- A data frame with 19 observations on the following 3 variables.
- weight : body weight of each rat in grams
- dose : relative dose of the drug given to each rat as a fraction of the largest dose
- liverdose : proportion of the dose in the liver
