As the number of significant figures increases, uncertainty decreases.a.Falseb.True

Information depletes the more it is used to resolve uncertainty. A. False B. True

Which of the following statements are true regarding the relationship between uncertainty, information and risk?Uncertainty increases with increase in experienceUncertainty reduces if the amount and quality of information is lowHigh experience and large amount of information results in less uncertaintyUncertainty is independent of the given information in any situation

How does increasing the degree of uncertainty affect the range of results expected to be obtained?

Economic uncertainty can lead to decreased consumer confidence and spending.Question 7Answera.Trueb.False

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.
