Which one of the following statements is true?Group of answer choicesOnly the quantities we measure directly have uncertainties; once we perform calculations with these quantities our answer is exact.If a height is recorded as h = (12 ± 3) mm, then it is absolutely certain that the height is between 9 mm and 15 mm.When we repeat a measurement many times and take the average value of these measurements, the uncertainty on this average (i.e. the SEM) is generally expected to be smaller than the uncertainty on the individual measurements.We only have uncertainties in first year lab because our equipment is not precise enough; in research labs there is no uncertainty.
