I could use some help understanding how to work through the questions.

A researcher conducts an experiment to examine the relationship between the weight gain of chickins whose diets had been supplemented by different amounts of amino acid lysine and the amount of lysine ingested . Since the* percentage of lysine is known , and we can monitor the amount of food consumed , we can determine the amount of lusine eaten . A random sample of twelve ?_ vice old chickens was selected for the study . Each was caged separately* and was allowed to cat at will from feed composed of a base supplemented with lysine . The ample data summarizing weight gains and amounts of lysine eaten over the test period are given below . I'm the data .
