Determine the upper-tail critical values of F in each of the following two-tail tests.
a. alpha =0.02, n1 = 10, n = 11
b. alpha =0.05, n = 10, n2 = 11
c. alpha =0.10, n1 = 10, n2 = 11

The Upper-tail critical values can be determined using Excel, the Excel F- functions: =F.INV.RT(probability, df1, df2), The degrees of freedom is n -1.

=F.INV.RT(0.02,9,10) = 4.044

alpha =0.05, n = 10, n2 = 11

=F.INV.RT(0.05,9,10) = 3.0204

alpha =0.10, n1 = 10, n2 = 11

=F.INV.RT(0.10,9,10) = 2.347
