Acube of iron and a cube of wood, each having a volume of v = 1.65 10-4 m3, are each placed in a large beaker of water. the density of the wood is ϝwood = 3.73 102 kg/m3 and the density of the iron is ϝiron = 7.86 103 kg/m3. calculate the buoyant force on each.

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
