A new process for producing synthetic gems yielded 11 stones weighing 0.43 0.48 0.49 0.51 0.47 0.43 0.53 0.54 0.54 0.48 0.5 in its first run. Summary statistics yield the sample mean 0.49 carat(s) and the sample standard deviation 0.04 carat(s). Construct and interpret a 99% confidence interval for the average carat weight of synthetic gems produced by the process. You may assume that the sample is from a normal population. i.
