Lab 2 provides two measurements that are within the required range (5.65-5.75%) and are also close to the actual value obtained from many measurements (5.6765%). Therefore, we can conclude that the values obtained from lab 2 are both accurate and precise, and can be used to verify that the beer sample meets the brand's specifications. The other labs provide either imprecise or inaccurate values, or values that are further away from the actual value, so they cannot be used to make any conclusions.
