Linda Jones, an accountant for Golding, Inc., has decided to estimate the fixed and variable components associated with the company's repair activity. She has collected the following data for the past six months: Repair Hours Total Repair Costs 10 20 15 12 18 25 $ 800 1,100 900 900 1,050 1,250 Required: 1. Estimate the fixed and variable components for the repair costs using the high- low method. Using the cost formula, predict the total cost of repair if 14 hours are used. 2. Estimate the fixed and variable components using the method of least squares. Translate your results into the form of a cost formula, and using that formula, predict the total cost of repairs if 14 hours are used. 3. Using the method of least squares, what are the coefficient of determination and the coefficient of correlation? 2. Regression is performed using Excel, with the results as follows: Summary Output Regression Statistics Multiple R R Square Adjusted R Square Standard Error Observations 0.984523 0.969285 0.961607 32.19657 6 ANOVA MS df SS F Significance F 126.2311 Regression Residual Total 0.000357 1 4 5 130853.5 4146.476 135000 130853.5 1036.619 Coefficients Standard Error Lower 95% Upper 95% Upper 95.0% Stat Lower 95.0% P-value Intercept X Variable 1 509.9119 29.40529 45.55789 11.19261 0.000363 383.4227 2.617232 11.23526 0.000357 22.13867 636.4011 383.4227 636.4011 36.6719 22.13867 36.6719
