To determine whether each question is a statistical question, we need to assess if the question anticipates variability in responses and would require data collection from multiple subjects to answer.

Here are the answers for each question:

  1. How much money do my friends spend on hobbies? - Yes
    This is a statistical question as it requires collecting data from multiple friends, and there will be variability in the amounts each friend spends.

  2. How many stamps has Valerie collected? - No
    This is not a statistical question because it pertains to a single individual (Valerie) and expects a specific answer rather than variability across multiple subjects.

  3. Does Lisa like knitting or karate better? - No
    This question is not statistical as it is asking for a preference of a single individual (Lisa) and will result in a single answer.

  4. How much time do my friends spend doing their hobbies? - Yes
    This is a statistical question as it involves multiple friends and anticipates variability in how much time each spends on their hobbies.

So, the final answers are:

  • How much money do my friends spend on hobbies? - Yes
  • How many stamps has Valerie collected? - No
  • Does Lisa like knitting or karate better? - No
  • How much time do my friends spend doing their hobbies? - Yes
