Nаilоr Cоmpаny is аccumulating data tо use in preparing its annual profit plan for the coming year. The cost behavior pattern of the maintenance costs must be determined. The accounting staff has suggested the use of linear regression to derive an equation for maintenance hours and costs. Data regarding the maintenance hours and costs for the last year and the results of the regression analysis follow: MonthMaintenance Cost (Y)Machine Hours (X) January$ 4,700680 February3,500520 March4,100600 April3,320500 May4,850700 June3,460510 July3,530520 August4,970760 September4,760690 October4,550670 November3,800550 December3,660540 a (intercept)$ 3.86 b (coefficient)6.7892 Standard error of the estimate83.417 R-squared0.9838 t-value for b24.668 1) The equation for the relationship between hours of activity and maintenance cost is:
