A financial analyst investigates the factors that are associated with the probability that a college student has certain credit cards. The analyst randomly samples college students for a survey. The survey asks the students questions about their education and finances.
After fitting the model, the analyst estimates the probability that a student who has $75 cash and an annual income of $10,000 has an American Express credit card.
Minitab uses the stored model to estimate that the probability is 0.3998. The confidence interval indicates that the analyst can be 95% confident that the probability falls within the range of approximately 0.07 to 0.85. This wide range indicates that the model does not produce precise predictions.
