the chartered financial analyst (cfa) designation is fast becoming a requirement for serious investment professionals. although it requires a successful completion of three levels of grueling exams, it also entails promising careers with lucrative salaries. a student of finance is curious about the average salary of a cfa charterholder. he takes a random sample of 36 recent charterholders and computes a mean salary of $158,000 with a standard deviation of $36,000. use this sample information to determine the 95% confidence interval for the average salary of a cfa charterholder. (you may find it useful to reference the t table. round final answers to the nearest whole number.)
