Is the time spent studying predictive of success on the CFA exam? The time spent studying for the CFA exam, in hours, and success, measured as Pass or Fail, are recorded for randomly selected students.

Dependent variable: Exam outcome (Pass or Fail); Independent variable: Time spent studying (in hours)

Would this be a simple linear regression model?

Correct Answer: Unlikely

The dependent variable is a binary outcome which violates the assumption of a normally distributed response at each level of X. Logistic regression is a more suitable for models with binary responses.
