Kids often don't want to tell their parents about the trouble they got into at school so they act like everything was normal even if it wasn't
Context: I asked my daughter how her day was at school and she totally played it off like she was there the entire day.
Hypothesis: I asked my daughter how her day was at schoool and she acted like she was there the whole day even though I know she was probably just fooling around

Is the hypothesis incorrect? (Yes, no, or unknown)?
