For those that did not come see me on Thursday or Friday afternoon and 
that are still needing help making the two trend lines:


Create you Excel spreadsheet and then copy the point for the lower trend 
line and the upper trend line into adjacent columns.


Then highlight all of the regions all the data and create a scatter 
plot.  Be sure to format the y-axis so it is not at zero.


Then select the lower values on the graph  to be fitted to a trend line  
(series 2 in this case) and then right click the mouse to add a trend 
line.   Do the same thing for the upper trend line.


And that's how you make multiple trend lines on the same graph.
