b. how many families in my neighborhood include children?

c. how many children are there in each family in my neighborhood?

d. how many children in my neighborhood have siblings?

e. how many families in my neighborhood have more than one child?

Explanation:

A statistical question is one that anticipates variability in the data.

• Option A: Just asks for a single count of children in the neighborhood. No variability expected.
• Option B: Just asks for a single count of families with children. No variability expected.
• Option C: Asks about the number of children in each family. Each family can have a different number of children (e.g., 1, 2, 3 etc.), so there is variability.
• Option D: Just asks for a single count of children with siblings. No variability expected.
• Option E: Just asks for a single count of families with more than one child. No variability expected.

Answer:

C. How many children are there in each family in my neighborhood?
