For the given combination of $\alpha$ and degrees of freedom (df), find the value of $\chi _ { ( 1 - \alpha / 2 ) } ^ { 2 }$ that would be used to find the upper endpoint of a confidence interval for $\sigma ^ { 2 }$. $\alpha = 0.01 , \mathrm { df } = 30$
A) $13.7867$
B) $14.9535$
C) $53.6720$
D) $13.1211$
