Your squad has been hired to verify suspicious claims across campus: bubble tea volumes, 5-km run times, exam durations and health-screening myths. Use p-values, critical regions and z-tests to climb the leaderboard.
Beat 10 mixed challenges. Correct answers earn points, streak bonuses and badges. Wrong answers unlock coaching prompts before you try again.
Learning targets: form hypotheses, choose tail type, calculate/compare p-values, interpret conclusions, and avoid “accept H₀”.
