State the Appropriate Null and Alternative Hypothesis and Find the Critical

State the appropriate null and alternative hypothesis and find the critical values for a two-tailed test with $\alpha = 0.10$ and $n = 8$ . Use $\sigma ^ { 2 } = 196$ .

A) $\mathrm { H } _ { \mathrm { o } } : \sigma ^ { 2 } = 196$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } \neq 196$
C. V. $= 2.733,15.507$

B) $\mathrm { H } _ { \mathrm { O } } : \sigma ^ { 2 } = 196$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } \neq 196$
C. V. $= 1.690,16.013$

C) $\mathrm { H } _ { \mathrm { O } } : \sigma ^ { 2 } = 196$
$\mathrm { H } _ { 1 : } \sigma ^ { 2 } \neq 196$
C. V. $= 2.180,17.535$

D) $\mathrm { H } _ { \mathrm { O } : } \sigma ^ { 2 } = 196$
$\mathrm { H } _ { 1 : } : \sigma ^ { 2 } \neq 196$
C. $\mathrm { V } . = 2.167,14.067$
