The number of spruce moths found in traps after 48 hours
was recorded. The traps were placed in different locations in the
tree (top, middle, lower branches, and ground) and different types
of lures were placed in the traps (scent, sugar, chemical). Use
Minitab, R, or your preferred statistical software to

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...
