The null hypothesis ($H_0$) always states that there is no effect or no difference, or it states the condition of equality. In this case, it would state that the variance is equal to 37.9. The alternative hypothesis ($H_1$) is what you are testing for, in this case, that the variance in the new section is greater than 37.9. Therefore, $H_0: \sigma^2 = 37.9$ and $H_1: \sigma^2 > 37.9$.
