Evaluates flight-delay quantification, modeling, and mitigation testing using historical operational data. Strong answers define delay metrics, model delay probability and severity, avoid leakage, and design valid experiments.

Scenario

Role-play as a data scientist asked to investigate flight delays for a major airline

Question

How would you quantify and model flight delays given historical departure and arrival data? Which statistical tests or confidence intervals would you use to determine if a new mitigation strategy has significantly reduced delays?

Hints

Consider distributions of delays, hypothesis testing, confidence levels, and regression or time-series models.
