Answer:
The investigation should not test the 10-year-old that declined.
Step-by-step explanation:
If a participant refuses to be in a study, the investigator must respect that declination and move on to another participating who is willing.
Omit the 10 year old child.
The researcher should honor the child's decision and carry out the study without the 10 year old child who firmly declined to be part of the research. A research (target) population must voluntarily concent to be in.
