In an experiment for this unit, theory predicts that the time take for a mass to roll down a slope will be 2.75 ± 0.05 s. Your repeated measurements of the speed gives a value of 2.40 ± 0.05 s. Are your measurements consistent with the theory?

Question

Answer

No, because within 3 x the standard uncertainties the values do not overlap.

Answer

Yes, because the values are within 10% of each other.

Answer

No, because within 2 x the standard uncertainties the values do not overlap.
