In an experiment for this unit, theory predicts that the speed of a cart, after rolling down a slope, will be 3.40 ± 0.08 ms -1 . Your repeated measurements of the speed gives a value of 3.7 ± 0.1 ms -1 . Are your measurements consistent with the theory?

Question

Answer

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

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.

Answer
