Suppose an auto club mails a flier to its members offering to send information on a supplemental heath insurance plan if the club member returns a brief form in an enclosed envelope. Why do some club members return the form and others do not? Can a model be developed to predict whether a club member will return the form? One theory is that the older people are more likely to return the form enquiring about additional health insurance because they are more concerned about their health and they have more disposable income to afford such coverage. Suppose a random sample of 92 club members is taken and club members are asked their age and if they have returned the form.
