The Department of Transportation claims that there is no difference between the variation of
federal highway money distributed to the northeastern states and the variation of federal money
distributed to the central states. The standard deviation for 11 northeastern states is 0.81 and the
standard deviation for 12 central states is 0.35. Using a 5% level, what is the critical value?
Solution
Critical Value
The Value of |F | at LOS 0.05 with d.f F(n1-1,n2-1)=F(10,11) is 3.526 ( Two Tailed Test).
