Problem 10E

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 µm 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.

Step by Step Solution

Step 1 of 2

Given,

Sample size, n = 15.

Mean track length,

Standard deviation,

Since confidence level is 99%, then
