Question

determining when a sample is appropriate which surveys would a sample be appropriate for? mark all that apply. helen wants to know the favorite sport of adults in her town. caleb wants to know the type of music his current teachers like. jaclyn wants to know the average weight of her sisters’ backpacks. kevin wants to know the most common way students get to school. roberto wants to know the average height of the people sitting at his table.

Explanation:

To determine which surveys a sample is appropriate for, we analyze each scenario:

Helen's Survey:

Helen wants to know the favorite sport of adults in her town. The population (all adults in the town) is large. Sampling (e.g., surveying a subset of adults) is appropriate to efficiently gather data without surveying every adult.

Caleb's Survey:

Caleb wants to know the type of music his current teachers like. The population (his current teachers) is small (likely a manageable number, e.g., 5–20 teachers). Sampling is unnecessary here—he can survey all teachers directly.

Jaclyn's Survey:

Jaclyn wants to know the average weight of her sisters’ backpacks. The population (her sisters’ backpacks) is small (e.g., if she has 2–5 sisters, their backpacks are a tiny group). Sampling is unnecessary; she can weigh all backpacks.

Kevin's Survey:

Kevin wants to know the most common way students get to school. The population (all students at his school) is likely large (e.g., hundreds of students). Sampling (surveying a subset of students) is appropriate to efficiently collect data.

Roberto's Survey:

Roberto wants to know the average height of people sitting at his table. The population (people at his table) is very small (e.g., 2–10 people). Sampling is unnecessary; he can measure everyone’s height directly.

Answer:

• Helen wants to know the favorite sport of adults in her town.
• Kevin wants to know the most common way students get to school.
