| robkaz | That is true for a 2-tailed test but not necessarily true for a 1-tailed test. |
| surob | I think it doesn't matter whether it is one tailed or 2 tailed. What matters here is that calculated F statistic is less than test statistic. |
| tom1980 | how about the null hypothesis you make ? |
| TheHTrader | Is the calculated F statistic = critical value (by looking up the table of f-distribution? I am a little confused here. |
| jpducros | For a F-Statistic, there is only a one-tail test possible, the right tail. |
I am using your study notes and I know of at least 5 other friends of mine who used it and passed the exam last Dec. Keep up your great work!
