On its website, the Statesman Journal newspaper (Salem, Oregon, 2005) reports mortgage loan interest rates for 30-year and 15-year fixed-rate mortgage loans for a number of Willamette Valley lending institutions. Of interest is whether there is any systematic difference between 30-year rates and 15-year rates (expressed as annual percentage rate or APR) and, if there is, what is the size of that difference. The following table displays the 30-year rate and the 15-year rate for each of nine lending institutions. Also given is the difference between the 30-year rate and the 15-year rate for each lending institution. Use the table to compare the 30-year rates and the 15-year rates. Also, calculate the average of the differences between the rates. (Input the amount as positive value. Round your answer to 4 decimal places.)
