The diameter of holes for a cable harness is known to have a normal distribution with a standard deviation of 0.01 inches. A random sample of size 10 yields an average diameter of 1.5045 inches. Find the 99% and 95% two-tailed/two-sided confidence intervals on the mean diameter and explain the difference of the interval between the two confidence levels.
