Quik Lube is a company that offers oil change service while the customer waits. Its market has been broken down into the following segments:
1. Working men and women too busy to wait at a dealer or service center
2. Spouses who work in the home
3. Retired persons
4. Other
A random sample of car owners was drawn. Each owner classified his or her market segment and also reported whether they usually use the services like Quik Lube (1 = Yes, 2 = No). These data are stored in stacked format.
a. Determine whether members of segment 1 are more likely than members of segment 4 to respond that they usually use the service?
b. Can we infer that retired persons and spouses who work in the home differ in their use of services such as Quik Lube?
