A person riding north on a bicycle speeds up from 0 m/s to 9 m/s in 3 seconds. The acceleration of the bicycle is m/s2.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
