Suppose a regession analysis provides the following results: bus0=4.0, bsub1=0.0, Ssubb0-1.0, ssubb1=4.0, SST=67.36, SSE=50.0 and n=20. Use this information to solve the following problembs:

a) Test the hypthesis Hsub0: Betasub0=0 , Hsuba:Betasub0 not equal to zero. Using the 5% level of significance. State the decision rule , the test statistic and your decision.

b)Test the hypothesis. Hsub0:Betasub1 less than or equal to 0, Hsuba: Betasub1>0 using a 5% level of significance. State the decision rule , the test statistic , and your decision . What can be drawn from the test result.
