Question
Airline companies are interested in the consistency of the number of babies on each flight, so that they have adequate safety equipment. Suppose an airline conducts a survey.

It determines the amount of safety equipment needed by the result of that study.

The sample was only taken on flights from Boston to Salt Lake City so it may not be representative of the population.
The sample included all babies on the flight, and they should have randomly selected a few.
The sample was taken only during the Thanksgiving holiday so more babies were likely to be traveling.
The sample included 6 flights, and they should have only sampled a single flight.
