Fission tracks are trails found in uranium-bearing minerals, left by fragments released during fission events. an article reports that fifteen tracks on one rock specimen had an average track length of 12 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. round the answers to three decimal places.

Mean track length for this rock specimen is between 10.463 and 13.537

Step-by-step explanation:

99% confidence interval for the mean track length for rock specimen can be calculated using the formula:

M± where

putting these numbers in the formula, we get confidence interval in 99% confidence as:

12± =12±1.537

Therefore, mean track length for this rock specimen is between 10.463 and 13.537
