Unformatted text preview: g. (b) No, the bias cannot be estimated, since we do not know the true value. 9. We can get a more accurate estimate by subtracting the bias of 26.2 g, obtaining 100.8 g above 1 kg. 11. (a) No, they are in increasing order, which would be highly unusual for a simple random sample. (b) No, since they are not a simple random sample from a population of possible measurements, we cannot estimate the uncertainty....
