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? The experiment appears to have uncovered a more accurato value of the boiling point. O It appears the data was collected accurately. OIt appears the data was collected inaccurately.
