Suppose that the production function is $q=L^{0.56} K^{0.48}$
a. What is the average product of labor, holding capital fixed at $\bar{K}$ ? $\mathbf{A}$
b. What is the marginal product of labor? (Hints:
See Solved Problem $6.1 .$ Calculate how much
$q$ changes as $L$ increases by 1 unit for a particular pair of $K$ and $L,$ use calculus, or see Appendix $6 \mathrm{C}$.) $\mathrm{C}$
