Thane Company is interested in establishing the relationship
between electricity costs and machine hours. Data have been
collected and a regression analysis prepared using Excel. The
monthly data and the regression output follow:
Month | Machine Hours | Electricity Costs | ||
January | 3,100 | $ | 18,700 | |
February | 3,500 | $ | 21,600 | |
March | 2,500 | $ | 13,800 | |
April | 3,700 | $ | 23,600 | |
May | 4,400 | $ | 28,550 | |
June | 3,900 | $ | 22,600 | |
July | 4,700 | $ | 25,050 | |
August | 4,100 | $ | 23,050 | |
September | 2,600 | $ | 16,100 | |
October | 4,300 | $ | 26,600 | |
November | 5,800 | $ | 31,600 | |

Intercept | 3,776.77 | 2,145.85 | 1.76 | 0.11 | (1,004.49) | 8,558.03 |
Machine Hours | 4.87 | 0.52 | 9.35 | 0.00 | 3.71 | 6.04 |
If the controller uses regression analysis to estimate costs, the
cost equation for electricity costs is:
Electricity Costs = $2,145.85 + ($0.52 × Machine-hours).
Electricity Costs = $1,753.98 + ($12.00 × Machine-hours).
Electricity Costs = $3,776.77 + ($2,145.85 × Machine-hours).
Electricity Costs = $3,776.77 + ($4.87 × Machine-hours).
Answer :
D) Electricity cost = $ 3,776.77+ ($4.87*Machine-Hours)
Regression Equation
Y= a+bx
Y= Cost
a= Intercept =Fixed cost
b= X-variable = Variable cost Per MH
From the Regression out put :
Electricity cost = $ 3,776.77+ ($4.87*Machine-Hours)
