Finding F-Critical (Comparing Variances)

  1. May 7, 2010 #1
    I'm in elementry statistics. For my paper, I have to do a hypothesis test that the variances for two samples with a count of 117 are equal. Easy enough, but I can't find any way of getting the f-critical values. NONE of the tables I've found with, say, 120 in it, has a left side. Thanks for any help...

    By "left" do you mean "F < 0"? If so that should not surprise you. By definition, F > 0.
