Although it requires a successful completion of three levels of grueling exams, the designation often results in a promising career with a lucrative salary.

He takes a random sample of 36 recent charterholders and computes a mean salary of $129,000 with a standard deviation of $22,000. Use this sample information to determine the 99% confidence interval for the average salary of a CFA charterholder.
