Answer:
The last option,
"Get a list of all the salons in her town and use a deck of cards to pick five of them to visit. Survey all the hairstylists that work at each salon."
Step-by-step explanation:
When choosing a survey, we want to ensure not only that the survey is time-effective and cost-effective, but that it is representative of the entire population.
Just choosing the salons close to her house would not necessarily be a good representation of the entire town.
Choosing salons that celebrities go to creates bias in the survey as well, as does choosing only the salons she and her friends go to.
However, finding a list of all salons and using a deck of cards to represent it creates a random sample; this helps to eliminate bias and ensure the sample is representative.
