Assume that everyone uses the same well-calibrated measuring device, such as a tape measure. Complete parts a through d below. a. All 25 measurements are not likely to be exactly the same; thus, the measurements will contain some sources of error. Are these errors systematic or random? Explain. A. These errors are systematic. If they were random, it would be undeterminable whether the measurements are all too high or too low. B. These errors are random. If they were systematic, there would be a tendency for the measurements to be all too high or all too low. C. These errors are random, because there is a tendency for the measurements to be all too high or too low. D.
