An artifact is found in a desert cave. the anthropologists who found this artifact would like to know its age. they find that the present activity of the artifact is 15 decays/s and that the mass of carbon in the artifact is 0.100 kg. what is the age of the artifact? be mindful of the units. remember that the fraction of radioactive carbon isotopes in a naturally-occuring sample of carbon is about 1.3×10−12. the question: what is the age of the artifact in years?

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
