Determine the upper-tail critical values of F in each of the following two-tail tests:
Á) á= 0.10, n1 = 16,n2 = 21
B) á = 0.05, n1= 16,n2 = 21
C) á= 0.01, n1 = 16,n2 = 21
You will need degrees of freedom to check for the critical values in the F-distribution table.
To calculate degrees of freedom (numerator):
k - 1
Note: k = number of levels.
To calculate degrees of freedom (demoninator):
N - k
Note: N = total number of values in all levels.
