Answer:
a) 65.74 ± 0.01
b) 60.009 ± 0.001
c) 66 ± 1
d) 65.750 ± 0.001
Explanation:
When reporting results, scientist usually specify a range of values that they expect this "true value" to fall within. The most common way to show this range of values is: measurement = best estimate ± uncertainty
Uncertainties are almost always quoted to one significant digit (example: ±0.05 s).
Wrong: 34.3 cm ± 4.3 cm
Correct: 34 cm ± 4 cm
Always round the experimental measurement or result to the same decimal place as the uncertainty.
Wrong: 1.237 s ± 0.1 s
Correct: 1.2 s ± 0.1 s
Therefore for to answer the question:
a) 65.74 ± 0.01
b) 60.009 ± 0.001
c) 66 ± 1
d) 65.750 ± 0.001
