[5 total pt(s)] Grey seals are capital breeders and stay with their pups until they are weaned. A group of researchers on Sable Island are interested in seeing whether there is a significant difference in the weight of one week old grey seal pups versus two week old pups. They measured the weight of 21 one week old pups, then weighed those same pups again one week later. The researchers found the average weight of adult female grey seals was...

A psychologist conducted an experiment to investigate the relationship between worker productivity (Y, measured in units of thousands of machine castings), salary incentive, shift (day or night), and type of factory (unionized or non-unionized). The salary incentive was the bonus paid per worker, in dollars, for castigs produced in excess of 100 over a four week period. The multiple regression model is γ=β0+pǐX1 + β2X2 + β3X3 + β4X1X2 + β5XiX3 + e, where Xi is the salary incentive, X,-1...
