　　John, FRM, and George, FRM, are discussing the hypothesis they wish to test with respect to the model represented by Yi = B0 + B1 × Xi + εi. They wish to use the standard statistical methodology in their test. George indicates an appropriate hypothesis to test is B1=1 with the goal of rejecting it. John indicates an appropriate hypothesis would be that B1=0 with the goal of proving it to be true. With respect to these hypotheses:
　　A.  The hypothesis of John is appropriate but not that of George.
　　B.  The hypothesis of George is appropriate but not that of John.
　　C.  The hypothesis of neither researcher is appropriate.
　　D. More information is required before a hypothesis can be set up.
　　Answer:B
　　The usual approach is to specify a hypothesis that the researcher wishes to disprove.
