I have this problem on Schweser.
The critical F-value for testing H0=b1=b2=b3=b4=0 vs. Ha: at least one bj is not equal to 0 at the significance level 5%. The # of observations are 65.
So I go back to F-Table to find the critical value. The # of independent variables which is 4 we can find from the top row of F-Table, and the # of observations we can find from the side row of F-Table, so the value is 2.53. That’s the answer.
My question is that what is the role of 5% significance level? It’s got nothing to do to find the answer. Right? We don’t really need the Significance level when we find F critical value or do the F-Test. Right?
