Question 130451: Please help me. I am stuck with this question.
A student team examined parked cars in four different suburban shopping malls. One hundred vehicles were examined in each location. Research question: At α = .05, does vehicle type vary by mall location?
Vehicle Type Somerset Oakland Great Lakes Jamestown Row Total
Car 44 49 36 64 193
Minivan 21 15 18 13 67
Full-sized Van 2 3 3 2 10
SUV 19 27 26 12 84
Truck 14 6 17 9 46

-----------------------------------
I ran a Chi-Sq Test on the data to examine
Ho: vehicle type does not vary by mall location
Ha: vehicle type varies by mall location
-------------------
Test statistic: Chi-Sq = 24.53
p-value = 0.017...
-------------
Conclusion:
Since p-value is less than alpha =is 5%, Reject Ho.
