The Answer of State the appropriate null and alternative hypothesis and find the critical value for a right-tailed test with $\alpha = 0.05$ and $n = 18$. Use $\sigma ^ { 2 } = 256$. A) $\mathrm { H } _ { \mathrm { O } } : \sigma 2 = 256$ $\mathrm { H } _ { 1 : } \sigma ^ { 2 } > 256$ C. $\mathrm { V } . = 27.587$ B) $\mathrm { H } _ { \mathrm { O } : } \sigma ^ { 2 } = 256$ $\mathrm { H } _ { 1 : } \sigma ^ { 2 } > 256$ C. $\mathrm { V } . = 28.869$ C) $\mathrm { H } _ { \mathrm { O } } : \sigma 2 = 256$ $\mathrm { H } _ { 1 : } \sigma ^ { 2 } < 256$ C. $\mathrm { V } . = 27.587$ D) $\mathrm { H } _ { \mathrm { O } } : \sigma ^ { 2 } \neq 256$ $\mathrm { H } _ { 1 : } \sigma ^ { 2 } < 256$ C. $\mathrm { V } . = 28.869$
