b. A 75-item lifestyle question set
c. A 30-item set of questions to determine whether the respondents are opinion leaders, sources of product information, and so on
d. A 40-item set of questions on the importance of bank services
e. A set of questions on usage of 35 bank services. Specifically, how would factor analysis be employed in this study?
