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. Over Thanksgiving weekend, it surveys 6 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.
Select the things that were wrong with the way the survey was conducted. (Select all that apply.)

O The survey uses systematic sampling.

O Conducting the survey on a holiday weekend will not produce representative results.

O Choosing 6 flights represents a stratified sample.

O The survey was conducted using six similar flights.

O The survey would not be a true representation of the entire population of air travelers.

Answer 1

Answer:

-Conducting the survey on a holiday weekend will not produce representative results

-The survey was conducted using six similar flights

-The survey would not be a true representation of the entire population of air travelers

Step-by-step explanation:

First of all, the sampling method that was used in this survey/study was a convenience sampling, were they just used the data that was readily available, which in this case were the 6 flights from Boston to Salt Lake City.

This sampling method is useful for pilot studies and for identifying tendencies, however, the obtained sample is not representative of the population, and because there is no criteria to organize the sample, (for example there was no fight with a different route taking into account) it is impossible to obtain statistical results that are precise.

And besides that, the fact that the survey was carried out over Thanksgiving weekend is also a factor that can directly affect the results, so it needs to be taken into account as a variable, which in this study was not.
