2. A simple curve that often makes a good model for the variable costs of a company, as a function of the number of units produced, x, has the form: y = b₁x + b₂x² + b3x³. (There is no constant term because fixed costs are not included.) Consider the following table of recorded variable costs versus units produced for some company:

URGENT PLEASE ANSWER ASAP The student was concerned that observation #45, which has an extremely large residual (~ -60), may be biasing their estimate of the slope of this relationship. Do you have this same concern? Why or why not?
Interpret the OLS coefficients (intercept and slope coefficients). When doing it, make sure to discuss the sign of the coefficient, its magnitude and ceteris-paribus interpretations, as well as statistical significance of the coefficients. First, discuss the approximate marginal effects. Next, calculate and discuss the exact marginal effects.
Suppose you believe that population abundance (A) of a particular species is a linear function of vegetation coverage (V) and the presence of a predators (P). Surveys where conducted across 20 sites and found the following information: a) There was an average of cover of .406 (40.6%) of the area, with an average 6.8 predators and 61.55 individuals in our target population. b) ⟨V2⟩=0.231⟨V2⟩=0.231, ⟨P2⟩=76.300⟨P2⟩=76.300, ⟨VP⟩=2.933⟨VP⟩=2.933, ⟨VA⟩=36.329⟨VA⟩=36.329, ⟨PA⟩=379.300⟨PA⟩=379.300 Set up the appropriate system of equations needed for a the linear regression of a model of the form A=aV+bP+cA=aV+bP+c. Then estimate the parameters and report the final model.
A manager uses the SLR model to study the relationship between price (X) and weekly demand (Y) of a certain product. She finds evidence of a linear relationship and wants an interval estimate for the mean weekly demand when the price is set at $25. We know: n = 5, X-bar = 20, sx² = 12.9, MSE = 12.3, and Y-hat = 100 - 3x 2 Use 3.2 as the critical value and find the margin of error (m.o.e.) for the interval. (Show 1 decimal place.)
For Shock G: Suppose the economy starts in the long run equilibrium. Illustrate changes that the shock will cause in the short run (using AD-SRAS). Explain why each curve shifts. Determine how the price level and output will be affected in the short run. Mark the output gap on the diagram. Is the output gap positive or negative? Is the economy is booming, or is it in a recession? On the same diagram illustrate how the economy will adjust to the shock in the long run and explain the mechanism. Determine how the price level and output will be affected in the long run. G. The government increases its spending on national defense As a result of this shock, in the short run the (SRAS Curve/AD Curve) will shift? In consequence, in the short run prices and output will? In the short run, there will be a ? (negative/postive) output gap,which means there will be a ? (boom/recession) As time passes, because of high unemployment the wages in the economy will?
