A team of students is collecting measurements of the boiling point of a liquid. The team determines a result of 37.0 ± 0.5°C. Through research, the team finds that the accepted value of the boiling point of the liquid is 37.4°C. Which conclusion can the team draw from this result?(1 point)
It appears the data was collected accurately.
The experiment should be continued until the team comes up with the exact result.
It appears the data was collected inaccurately.
The experiment appears to have uncovered a more accurate value of the boiling point.
