Use the following regression results to answer the four questions below. Dependent Variable: Q Observations: 32 R2- 0.7547 F-ratio: 92.31 p-ratio on F: 0.0001 Variable Parameter Estimate Standard Error t-ratio p-value -0.0016 0.0005 -3.20 0.0032 0.4000 0.0950 4.21 0.0002 Which of the following equations is derived correctly? Select one: O a MP= -0.004813 + 0.8000L O b. AP = 0.00053343 - 0.1333L O c. Q= -0.0016/* + 0.400023 + 0.0005L + 0.7547 O d. AP= -0.003213 + 0.80001 The coefficient estimates above are statistically significant at the 10% level. Select one: O True O False The slope of the AP curve is found by . ; AP is maximized at units of labor. Select one: O a -0.003213 + 0.2L L = 62.5 O b. -0.001613 + 0.4L L = 250 O c. -0.0096L + 0.8 L = 83.33 O d. -0.00324 + 0.4 L = 125
