Three groups perform identical measurements to determine the enthalpy of combust

Question

Three groups perform identical measurements to determine the enthalpy of combustion of benzene. Each group reports a mean and standard deviation: What is the best estimate of the overall value (including standard deviation) of the enthalpy, based on these measurements? ANSWER: ___ C. The CRC Handbook reports a value -3266 kJ/mol for the enthalpy of combustion of benzene. Looking at the results from part B, which is better in this experiment: accuracy or precision? Be quantitative in your explanation. ANSWER:___ Explanation:

Explanation / Answer

(B)

Original entahlpy of Combustion of Benzene is -3266 kJ/mol

So according to this value Group of A is nearer that value.So I think -3800 kJ/mol is best value.
