Problem 8E

The Kilogram is now weighed five times on a different scale. The measurements are as follows, in units of micrograms above 1 kg: 25.6, 26.8, 26.2, 26.8, 25.4.

a. Is it possible to estimate the uncertainty in these measurements? If so, estimate it. If not, explain why not.

b. Is it possible to estimate the bias in these measurements? If so, estimate it. If not, explain why not.

Solution:

Step 1 of 3:

The weight of 5 measurements in units of micrograms above 1kg is given as 25.6, 26.8, 26.2, 26.8, 25.4(micrograms).

We have to check

- Is it possible to estimate the uncertainty in the measurements.
- Is it possible to measure the bias in this measurements.
