The Behrens-Fisher problem is that of comparing the means of two populations when the ratio of their variances is unknown. Solutions are discussed in terms of interval estimation and testing. Of the six solutions compared, three are preferred by the writer and judged practical, and for these, approximations are given for the power of the tests.
