Following a regression analysis, an examination of graphical plots was performed to determine whether the assumptions for are appropriate. consider the following plot from this analysis: what type of plot is this? a. a plot of the residuals against the predicted values of the dependent variable b. a plot of the residuals against values of the dependent variable c. a plot of the standardized residuals against values of the independent variable d. a normal probability plot

Suppose that a paving company produces paved parking spaces (q) using a fixed quantity of land (t) and variable quantities of cement (c) and labor (l). the firm is currently paving 1,000 parking spaces. the firm's cost of cement is $3 comma 600.003,600.00 per acre covered (c) and its cost of labor is $35.0035.00/hour (w). for the quantities of c and l that the firm has chosen, mp subscript upper c baseline equals 60mpc=60 and mp subscript upper l baseline equals 7mpl=7. is this firm minimizing its cost of producing parking spaces?
