The Chartered Finaralal Analyst (CFA) designation is fast becoming a requirement for serious investment professionals. Although it requires a successful completion of three levels of grueling exams, the designation often results in a promising career with a lucrative salary. 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 $182,000 with a standard deviation of $48,000. Use this sample information to determine the 90% confidence interval for the average salary of a CFA charterholder. Assume that salaries are normally distributed. (Round intermediate calculations to at least 4 decimal places. Round t value to 3 decimal places and final answers to the nearest whole number.)
