Fission tracks are trails found in uranium-bearing
Chapter 5, Problem 10E(choose chapter or problem)
Fission tracks are trails found in uranium-bearing minerals, left by fragments released during fission events. The article “Yo-yo Tectonics of the Nigde Massif During Wrenching in Central Anatolia” (D. Whitney, P. Umhoefer, et al., Turkish Journal of Earth Sciences, 2008:209-217) reports that fifteen tracks on one rock specimen had an average track length of 13 \(\mu m\) with a standard deviation of 2 µm. Assuming this to be a random sample from an approximately normal population, find a 99% confidence interval for the mean track length for this rock specimen.
