Question

A particular brand of beer must maintain an alcohol content by volume of 5.65 to 5.75%. Analyses at four independent labs of an artificial beer sample with an alcohol content of 5.68% by volume yielded the following data. What can be deduced from these results? a. The data from lab 4 should be used based on its precision. b. The values from lab 1 are both imprecise and inaccurate. c. Lab 2 provides sufficiently precise and accurate values. d. The values from lab 3 are sufficiently precise and accurate. e. None of the data meet the brewers specifications.

Explanation / Answer

c. Lab 2 provides sufficiently precise and accurate values.

As the lab 2 data provides 3rd decimal value and other lab only one decimal value or no decimal value. So the Lab -2 data is more reliable data.
