Slowly move the Productivity Index slider right and then left again. Observe the changes in the table and the graph to answer the following questions: a. By how much does the output from four workers increase when productivity increases by 25% (the index moves from 0% to 25%)? units b. By how much does the output from five workers increase when productivity increases by 25% (the index moves from 0% to 25%)? units c. How is this increase shown on the production function graph (top graph)? (Click to select) d. By how much does the marginal product of the fifth worker increase when productivity increases by 25% ? units e. How is this increase shown on the marginal product graph (bottom graph)?
