------
Find the relative frequency for each # of franchises::
Example:: Relative freq for 13 = 13/92 = 0.1585
----
Multiply each relative freq by the corresponding dollar figure
Ex:: 0.1585 * 100 = 15.85
-----
Find the sum of the products to get the expected product::
E(x) = (13*100 + 15*200 + 23*300 + 9*400 + 10*500 + 22*600)/92
