Calculating F-distribution probability without tables (Hypothesis problem)
$begingroup$
During a total solar eclipse the temperature drops quickly as the moon passes
between the earth and the sun. These data are obtained on the drop in
temperature in degrees Fahrenheitat two types of locations in southern Africa
during the June 2001 eclipse:
Mountainous terrain: 15, 12, 16, 16, 13, 15, 11, 19, 15
River-level terrain: 13, 17, 19, 16, 15, 19, 18, 20, 21, 22, 24
Is there evidence at the a = 0.20 level of significance that there is a
differencein the variances in temperature drop seen in these two terrains?
This is the whole question for the one who is intrested. It boils down to solving this (I think):
$P(F(10,8)>1.79)$, where $F$ denotes the F-distribution. The tables have nothing on this, how do I solve it? Do I have to do some kind of force majeure solution, looking at the defintion of the F- distribution probabilty function?
