$$\begin{array} { l } 
H _ { 1 } : \sigma < 0.14 \
n = 23 \
\alpha = 0.10
\end{array}$$
A) 30.813
B) 14.848

Since we have a one-tailed test with a lower limit, we need to use the chi-square distribution table for lower tail area. Using it with a degree of freedom of 22 (n-1), we find the critical value to be 14.042 at a significance level of 0.10. Therefore, the answer is C.
