Answer:
a(I).Q4, (ii). W3.
(b). Q4.
(c). (i) and (ii). Check Explanation
Explanation:
Note: Kindly check the attachment for the graph. The solution to the question is given below;
(a). Using the labels from the graph above, identify each of the following.
(i) The optimal quantity of labor Larry’s Lumber Mill will hire will be at a point in which marginal cost = marginal revenue which is point Q4
(ii). The wage rate Larry’s Lumber Mill will pay is at a point in which the Marginal revenue = marginal cost that is at point W3.
(b). Using the labels from the graph above, the number of workers Larry’s Lumber Mill would hire if the labor market were perfectly competitive is Q4.
(c). (i). Larry’s Lumber Mill’s demand for labor increase which will cause a shift to the right on the demand curve. This is so, because as the demand for housing increases, the demand for lumber will increase too.
(ii). The supply is lesser than the demand which will cause a shift to the left on the supply curve.
Finding the new mean is simple: If , then
.
Meanwhile, the standard deviation is the square root of the variance, which is given by
and so the new standard deviation would be .
