Assume the following data (wh the xxx is the last three digin your panther id): For example, if your panther id is 123.4567, then machine hours would be 1240 bours and your maintenance costs would be $100,567 in month 1;1400 hours and $107,567 is month 2;1600 hours and $113,567 in month 12 . Assume that the following relationship holds: Maintenance Costs =a+(b Machine Hours ) REQUIRED Estimate the values of a and b, using, 1. the High-Low Method, and 2. the Linear Regression method (12 Points) For help outside of the textbook, try "I inear Regression in Excel" on YouTube Note, to use the lincar regression method, you MUST use the Microsoft Excel program. Make sure to report i). the values of a and b ii) a scatter plot of the data points, and iii) the R-square or the adjusted R-square 3. Which of the above two methods is more appropriate? Why?
