Welcome to your interview.
The question is on your right: Sample Size and Minimum Detectable Effect. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain how you would estimate sample size and minimum detectable effect for an experiment in an insurance product at One Alliance Insurance Managers.
