Let’s say there is man who is 5.8 feet tall who doesn’t know how to swim. Let’s say he wants to swim in a lake with an average depth of 5.6 feet with a standard deviation of 1 foot.

What’s the probability of his survival assuming that when the the lake depth exceeds his height, he dies?

Swimmer Survival

Suppose there exists a new airline named Jetco that flies domestically across North America. Jetco recently had a study commissioned that tested the boarding time of every airline, and it came out that Jetco had the fastest average boarding times of any airline.

What factors could have biased this result, and what would you look into?

What could potentially bias the average boarding time in favor of an airline that only flies domestically?

What could potentially bias the average boarding time in favor of an airline that only flies domestically?

Boarding Times Bias

A new airline came out as the fastest average boarding times compared to other airlines.  What factors could have biased this result and what would you look into?

Explain how a probability distribution could not be normal and give an example scenario.
