Four students divided the task of surveying the types of vehicles in parking lots of four different shopping malls. Each student examined 100 cars in each of three large suburban Detroit malls and one suburban Jamestown, New York, mall, resulting in the 5 3 4 contingency table shown below.
(a) Calculate each probability (i­vi) and explain in words what it means.
(b) Do you see evidence that vehicle type is not independent of mall location? Explain. (Data are from an independent project by MBA students Steve Bennett, Alicia Morais, Steve Olson, and Greg Corda.)
i. P(C)
ii. P(G)
iii. P(V | S)
iv. P(C | J )
v. P(C and G)
