A Sample Standard Deviation and Sample Size Are Given $\mathrm { s } = 13.1 , \mathrm { n } = 22$

Multiple Choice

A sample standard deviation and sample size are given. Use the one-standard-deviation x²-test to conduct the requiredhypothesis test.
- $\mathrm { s } = 13.1 , \mathrm { n } = 22$
$\mathrm { H } _ { 0 } : \sigma = 16.1 , \mathrm { H } _ { \mathrm { a } } : \sigma < 16.1 , \alpha = 0.01$

A) Test statistic: $\mathrm { X } ^ { 2 } = 13.903$ . Critical value $= 8.897$ . Do not reject $\mathrm { H } _ { 0 }$ .
B) Test statistic: $\mathrm { X } ^ { 2 } = 13.903$ . Critical value $= 8.897$ . Reject $\mathrm { H } _ { 0 }$ .
C) Test statistic: $X ^ { 2 } = 13.903$ . Critical value $= 38.932$ . Reject $\mathrm { H } _ { 0 }$ .
D) Test statistic: $\mathrm { X } ^ { 2 } = 13.903$ . Critical value $= 38.932$ . Do not reject $\mathrm { H } _ { 0 }$ .
