test the claim about the differences between two population variances a21 and a22 at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent samples that are randomly selected and each population has a normal distribution.
claim a21>a22, a=0.01
sample statistics: s21=921, n1=6, s22=655, n2=11

A21 &gt; a22 , α = 0.01
S21 = 921 , N1 = 6
S22 = 655 ,N2 = 11
H1 : a21 &gt; a22
d.f.N = 20
d.f.D=20
since α = 0.01 , critical value = 3.31
Test Value F = S12 / S22 F = (921)2 / (655)2
F = 848241...
