a. Which variable is the independent variable? Which is the dependent variable?

b. Draw a scatter diagram illustrating this relationship. Draw a (nonlinear) curve that connects the points. Put the hourly wage rate on the vertical axis.

c. As the wage rate increases from $15 to $30, how does the number of hours worked respond according to the rela- tionship depicted here? What is the average slope of the curve between Athena's and Boris's data points using the arc method?

d. As the wage rate increases from $60 to $75, how does the number of hours worked respond according to the rela- tionship depicted here? What is the average slope of the this diagram? Suppose you reverse what is measured on the two axes. What is the argument made then?
