American property bubble-SOF

The bursting of the American property bubble showed that a rapid rise in home prices and household debt,
built on a foundation of low interest rates and easy mortgages, could be a toxic combination. When the
boom ended, it left a legacy of failed banks, foreclosed homes, recession and government debt.
Given the situation, the Maritime Community Bank (MCB) wanted to evaluate its mortgage/loan policies,
and randomly selected 500 recent loan/mortgage applicants. In the table below, the data is classified
according to their credit rating--excellent (E), good (G), fair (F) or poor (P)--and their place of residence--
Metro region (M), Cape Breton (C), or Western NS (W).
