Regression analysis, multiple choice. Lorenzo Company estimated the behavior pattern of maintenance costs. Data regarding maintenance hours and costs for the previous year and the results of the regression analysis follow:

a. In the equation TC = F + VX, the best description of the letter V is as the (1) independent variable.
(2) dependent variable.
(3) variable cost coefficient.
(4) coefficient for the intercept.

b. The best description of TC in the preceding equation is as the (1) independent variable.
(2) constant coefficient.
(3) dependent variable.
(4) variable coefficient.

c. The best description of the letter X in the preceding regression equation is as the ( 1 ) dependent variable.
(2) coefficient for the intercept.
(3) variable cost coefficient.
(4) independent variable.

d. Based on the data derived from the regression analysis, 200 maintenance hours in a month mean that the maintenance costs would be estimated at (1) $3,680.
(2) $3,600.
(3) $3,461.
(4) $3,797.
(5) Some other amount.
