    i thought i could use the F table to look up critical value (at the 0.95 level), but have become stuck

    I'm trying to look up F~28,21
    But the columns only normally go upto 19. I need 28. How do i find it?

    Thanks

    im pretty sure that we have to use what weare given (as we are give the same tables in the exam) and it only goes upto 19, but then in followed by the infinity symbol.

    well I'm on Edexcel and their tables aren't much better. I wouldn't worry, if you are doing A level at least they will ALWAYS give you ones that are in the stat tables in the formula booklet.
