(4 Points)
The true average must be exactly 2.9 hours.
The true average is probably between 2.8 and 3.1 hours.

1 answer
The most reasonable conclusion based on the data provided is:
The true average is probably between 2.8 and 3.1 hours.
This choice acknowledges that the averages from the three samples are relatively close together, suggesting that the true average could reasonably lie within this range. The other options either make unfounded claims or suggest unreliability without sufficient justification.
