Question

a toy store owner tracking how much kids spend each month on toys. which choice best represents a sample? all of the kids who buy toys 277 rich kids 257 boys age 7 - 15 206 kids from age 10 to 15

Explanation:

Step1: Understand the concept of a sample

A sample is a subset of a population. In this case, the population is all kids who buy toys.

Step2: Analyze each option

• "All of the kids who buy toys" is the population, not a sample.
• "277 rich kids" is a subset based on a non - relevant (for a general kids' toy - spending sample) characteristic (wealth).
• "257 boys age 7 - 15" is a subset based on gender and a restricted age range.
• "206 kids from age 10 to 15" is also a subset with a restricted age range. But if we assume we want a sample that is more likely to be representative (assuming no other biases), a sample that is just a subset of the population (all kids who buy toys) without extra non - general (like wealth or gender) restrictions (even though the age range is still a restriction) is better. However, if we consider the fact that in statistics, a sample should be a subset of the population of interest. The population is all kids who buy toys. Among the options, "206 kids from age 10 to 15" is a subset (a sample) of the population (all kids who buy toys)

Answer:

206 kids from age 10 to 15
