State the Appropriate Null and Alternative Hypothesis and Find the Critical

State the appropriate null and alternative hypothesis and find the critical value for a left-tailed test with $\alpha = 0.10$ and $n = 23$ . Use $\sigma ^ { 2 } = 225$ .

A) $\mathrm { H } _ { \mathrm { O } : } \sigma ^ { 2 } = 225$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } < 225$
C. $\mathrm { V } . = 14.042$

B) $\mathrm { H } _ { \mathrm { O } } : \sigma ^ { 2 } = 225$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } < 225$
C. $\mathrm { V } . = 14.848$

C) $\mathrm { H } _ { \mathrm { O } } : \sigma ^ { 2 } = 225$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } > 225$
C. $\mathrm { V } . = 14.042$

D) $\mathrm { H } _ { \mathrm { O } : } \sigma ^ { 2 } = 225$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } > 225$
C. $\mathrm { V } . = 14.848$
