Data, Sampling, and Variation in Data and Sampling · Exercise 46

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. Over Thanksgiving weekend, it surveys six flights from Boston to Salt Lake City to determine the number of babies on the flights. It determines the amount of safety equipment needed by the result of that study.

(a) Using complete sentences, list three things wrong with the way the survey was conducted.
(b) Using complete sentences, list three ways that you would improve the survey if it were to be repeated.
