Given the following information about a hypothesis test of the difference between two variances based on independent random samples,what is the calculated value of the test statistic? Assume that the samples are obtained from normally distributed populations.
H_A: ?²_A > ?²_B, $\bar { X }$
₁ = 12, $\bar { X }$
₂ = 9,s₁ = 5,s₂ = 3,n₁ = 13,n₂ = 10.

Given the following information about a hypothesis test of the difference between two variances based on independent random samples,what is the calculated value of the test statistic? Assume that the samples are obtained from normally distributed populations.
H_A: ?²_A > ?²_B,

\bar { X }

₁ = 12,

\bar { X }

₂ = 9,s₁ = 5,s₂ = 3,n₁ = 13,n₂ = 10.
