Explain confidence limits for the average sulfur content

Reference no: EM13275365

The following results were obtained for the determination of sulfur in another coal sample. The average for 3 trials was 2.28 %S. Report the 95% confidence limits for the average sulfur content in this sample based on the knowledge from extensive previous experience that the standard deviation is equal to 0.10 %S.
