Ho: Row and column factors are independent
Ha: Row and column factors are dependent
--------------
Run a Chi-Sq Test on the 5 by 4 set of data to get:
Chi-Sq = 24.53
p-value = 0.0172
df = (4*3) = 12
-----------------------
Conclusion:
Since the p-value is less than 5%, reject Ho.
The Row and column factors are dependent ; vehicle type
varies by location.
