Answer :
To ensure data precision the trials that should be discarded are Trial 4 (96.5) and Trial 7 (107.5).
Trials to be discarded
To determine the trials that should be discarded to make the data precise, identify any outliers or values that significantly deviate from the others.
Outliers can arise due to measurement errors, equipment malfunctions, or other factors.
The given results for the boiling point values of water are as follows:
Trial 1: 100.1
Trial 2: 99.9
Trial 3: 100.2
Trial 4: 96.5
Trial 5: 100.0
Trial 6: 99.9
Trial 7: 107.5
By observing the data, we can identify Trial 4: 96.5 and Trial 7: 107.5 as values that deviate significantly from the other trials.
These values appear to be outliers compared to the rest of the measurements.
To ensure data precision, it is advisable to discard these outlier values. Therefore, the trials that should be discarded are Trial 4 (96.5) and Trial 7 (107.5).
