Suppose the regression line μy=10000+962x models the relationship for the population of working adults in a certain country between x= age and the mean of y= annual income. The conditional distribution of y at each value of x is modeled as normal with σ=6000. Use this regression model to find the mean y-value for age 23 years.

Find the equation for the tangent to the graph of $ y $ at $ \left(5, \frac{\pi}{6}\right) $. \[ y=\sin ^{-1}\left(\frac{x}{10}\right) \] The equation of the line tangent to the graph of $ y $ at $ \left(5, \frac{\pi}{6}\right) $ is $ y= $ $ \square $ 1. (Use integers or fractions for any numbers in the expression. Type an exact answer, using radicals as needed.)

Lorenzo and Neha are partners at an architecture firm. They are trying to determine which of them has a comparative advantage in building the 50 models required for a sales pitch to a prospective client. Lorenzo can build 10 models per hour. For other activities, he can bill clients $500 per hour. Lorenzo's opportunity cost of building models is $50 per model. Neha's opportunity cost of building models is 20% higher than Lorenzo's. However, as the junior partner, her billing rate is 15% lower. Based on all of these facts, Lorenzo has a comparative advantage in building models.

What is an error-correction model? Suppose $y_t$ and $x_t$ are I(1) cointegrated variables where the relationship between the variables may be correctly modelled as $y_t = \beta_0 + \beta_1 x_t + u_t$ where $u_t$ is a white noise disturbance term. Describe fully the Error Correction Mechanism (ECM) for the system of variables. Comment on the economic interpretation of the parameters. (10 marks)
