Unit review questions
1. Choose the age-specific reference correctly: The fictional participant is 17. Which fits?
Need a hint?
  • Select guidance by stated age, not school grade.
  • Daily youth and weekly adult references are not interchangeable.
2. Sum an adult weekly aerobic model: Fictional case 5: minutesPerBlock=35, distinctBlocks=4. What is the modeled result using the stated method?
Need a hint?
  • Aerobic minutes do not establish muscle-strengthening days.
  • This weekly model is for an explicitly adult participant, not a 16 year-old.
3. Use adult moderate-equivalent minutes: Fictional case 5: moderateMinutes=120, vigorousMinutes=15. What is the modeled result using the stated method?
Need a hint?
  • Equivalent minutes are a planning conversion, not extra elapsed time.
  • This combination model is explicitly for adults; muscle days remain separate.
4. Report which guidance checks remain unknown: An adult’s equivalent aerobic total is 150 and muscle records are absent. What fits?
Need a hint?
  • One component cannot stand in for another.
  • A completed schedule does not prove the planned activity happened.

Use the skills in a new task

Compare a fictional 17 year-old with only a weekly average and a 20 year-old with 90 moderate+30 vigorous minutes, but no muscle-day record.

Work on paper or in your own document. Explain the choices you made.

  • Use the supplied facts without personal disclosures.
  • Apply at least two methods from this unit.
  • Show the sequence, calculation or evidence behind the decision.
  • Include a relevant boundary, help step or accessible alternative.
Compare with a model response

Youth daily coverage is unknown from an average. The adult equivalence is 90+2*30=150 moderate-equivalent minutes, while clock time is 120 minutes. Muscle days and actual participation remain unknown. Keep ages explicit and allow paper-only completion.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
