Final answer:
The bias in the measurement is 2 g, and the uncertainty in the measurement is 4 g.
Step-by-step explanation:
To determine the bias and uncertainty in the measurement made on the certain scale, we need to understand the terms. Bias refers to a constant value that is added or subtracted from the true value. In this case, the bias is 2 g. Uncertainty, on the other hand, refers to the range within which the measurement can vary. In this case, the uncertainty is 4 g.
Therefore, the bias in the measurement is 2 g, and the uncertainty in the measurement is 4 g.
