Thаne Cоmpаny is interested in estаblishing the relatiоnship between electricity cоsts 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 2,700 $ 19,300 February 3,100 22,800 March 2,100 14,400 April 3,300 24,800 May 4,000 29,150 June 3,500 23,800 July 4,300 25,650 August 3,700 23,650 September 2,200 17,300 October 3,900 27,800 November 4,900 32,800 December 4,400 28,650 Summary OutputRegression Statistics Multiple R 0.954 R Square 0.911 Adjusted R2 0.902 Standard Error 1,645.83 Observations 12.00 Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 3,979.06 2,054.03 1.94 0.08 (597.59) 8,555.71 Machine-Hours 5.76 0.57 10.11 0.00 4.49 7.03 If the controller uses regression analysis to estimate costs, what is the cost equation for electricity costs?
