Question 2) A shopping mall that wishes to evaluate its image places packets including a questionnaire, cover letter, and stamped return envelope in the mall where customers can pick them up if they wish.

Question 3) An e-mail message is sent to individuals who own computers, asking them to complete a questionnaire on a Web site. Respondents answer the questions and then have the opportunity to play a slot-machine game on the Web site. Each respondent is guaranteed a monetary incentive but has the option to increase it by playing the slot-machine game.

Question 4) A mall intercept interviewing service is located in a regional shopping center. The facility contains a small room for television and movie presentations.
