A potato chip manufacturer has two packaging lines and wants to determine if the variances differ between the two lines.They take samples of n₁ = 10 bags from line 1 and n₂ = 8 bags from line 2.To perform the hypothesis test at the 0.05 level of significance,the critical value is F = 3.68.

The critical value for an F-test depends on the degrees of freedom for the numerator and denominator, which are (n1-1) and (n2-1) respectively. For df1 = 9 and df2 = 7 at the 0.05 significance level, the critical value is not 3.68.
