Problem 2

Kyra, Amit, and Ben are discussing the results of two experiments that have measured the speed of a car in cm/s. The means and uncertainty intervals are shown below.

Kyra says: 'The measurements do not agree with each other because the mean values are outside the overlapping uncertainty interval.'

Amit says: 'The measurements do not agree because the mean values are different.'

Ben says: 'The measurements agree because the uncertainty intervals overlap.'
