Essay

Random samples from two normal populations produced the following statistics: $n _ { 1 } =$ 10, $s _ { 1 } ^ { 2 } =$ 40. $n _ { 2 } =$ 15, $S _ { 2 } ^ { 2 } =$ 20.
Is there enough evidence at the 5% significance level to infer that the variance of population 1 is larger than the variance of population 2?
