1)Prepare a scatter graph of Odie Company operating cost and draw the line you believe best fits the data.

2)Based on this graph estimate Odie Company total fixed cost per month.

3)Using the high and low method, calculate Odie Company total fixed operating costs and variable operating costs per window. (Use the number of windows as the output)

4)Using the high and low method results, calculate the expected operating cost for the business if it paints 75 windows.

5)Run a simple regression with the operating cost as the y variable and number of windows as the x variable.

6)What is the estimate total fixed costs, what is the variable cost per display.
