--------------------------------------------------------------
Chi-Sq Test
Ho: row and column factors are not related
Ha: they are related or dependent
--------------------------------------
Run a Chi-Sq Test to get:
Test Stat: 24.5315...
p-value:0.0172...
df=(5-1)(4-1) = 12
Conclusion:
Since p-value is less than 5%, reject Ho
There is a relation between car type and location
