A scholar has found a purportedly ancient scrap of papyrus that contains a controversial fragment of text. To verify its supposed 1600-year age, a small sample that contains 50 mg of carbon is removed and analyzed by radio-carbon dating, in which decays of $^{14}C$ are counted. If $^{14}C$ has a mean lifetime of 8270 years, and the normal abundance of $^{14}C$ in living matter (like reeds from which papyrus is made or charcoal used as an ink) is 1.2 parts per trillion ($1.2 \times 10^{-12}$), find the expected count rate for the 50 mg sample if it is indeed 1600 years old. If the measurement is made over a 24-hour period, what is the statistical uncertainty on the age of the sample? Assume the mean lifetime and $^{14}C$ abundance is known precisely. [Hint: the statistical uncertainty on the number of decays observed, $N$, is $\sqrt{N}$.]
