It is an attractive alternative to getting an MBA for students wanting a career in investment. A student of finance is curious to know if a CFA designation is a more lucrative option than an MBA. He collects data on 41 recent CFAs with a mean salary of $146,000 and a standard deviation of $53,000. A sample of 52 MBAs results in a mean salary of $133,000 with a standard deviation of $26,000. Assume that μ1 is the population mean for individuals with a CFA designation and μ2 is the population mean of individuals with MBAs.
