Question

The owner of a moving company typically has his most experienced manager predict the total of labor hours that will be required to complete an upcoming move. This approach has proved useful the past, but the owner would like to develop a more accurate method of predicting the labor hours using the number of cubic feet moved and whether there is an elevator in the building. by In a preliminary effort to provide a more accurate method, he has collected data for 36 moves and has developed the following regression equation: Y 2.50 .05.Xi -3.00X where x amount of cubic feet moved Xa for elevator and 0 for no elevator Y- man hours of labor ANSWER QUESTIONS 6-3 ON THE BASIS OF THE ABOVE

Explanation / Answer

Labour hours,Y = 2.5+0.05X1 -3 X2

According to question, X1 = 500 and X2 = 1

Y = 2.5 + 0.05 * 500 -3 (1) = 2.5+25-3 = 24.5

Hence,24.5 hours will be required
