O Fail to reject H,
What is your final conclusion?
O The evidence supports the claim that one ar more of the regression coefficients is non-zero
O The evidence supports the claim that all of the regression coelfficients are zero
OThere is insufficient evidence to support the claim that at least one of the regression coefficients is non-zero
O There is insufficient evidence to support the claim that all of the regression coefficients are equal to zero
