My Panther ID is: 6177391; so for the sake of this exercise 391 will be used to complete the maintenance cost numbers.

Assume the following data (where the xxx is the last three digits of your panther id):

For example, if your panther id is 1234567, then your maintenance costs would be $103,567 in month 1; $107,567 is month 2; $113,567 in months 10, 12, and 13.

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(12 Points)

2. the Linear Regression method (12 Points)

For help outside of the textbook, try "Linear Regression in Excel" on YouTube

Note, to use the linear 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 ?
