Random samples from two normal populations produced the following statistics: $n _ { 1 } =$ 25, $s _ { 1 } ^ { 2 } =$ 75. $n _ { 2 } =$ 13, $S _ { 2 } ^ { 2 } =$ 130.
Briefly describe the 95% confidence the ratio of the two population variances:
LCL = ( $s _ { 1 } ^ { 2 } /$ $S _ { 2 } ^ { 2 }$ ) / F_0.025,24,12 = 0.191.
UCL = ( $s _ { 1 } ^ { 2 } /$ $S _ { 2 } ^ { 2 }$ )F_0.025,12,24= 1.465.

Question
