A Sample Standard Deviation and Sample Size Are Given $\chi ^ { 2 }$

Multiple Choice

A sample standard deviation and sample size are given. Use the one-standard-deviation $\chi ^ { 2 }$ -test to conduct the requiredhypothesis test.
- $\mathrm { s } = 2.4 , \mathrm { n } = 17$
$\mathrm { H } _ { 0 } : \sigma = 3.5 , \mathrm { H } _ { \mathrm { a } } : \sigma \neq 3.5 , \alpha = 0.10$

A) Test statistic: $X ^ { 2 } = 7.523$ . Critical values $= 7.962,26.296 .$ Reject $\mathrm { H } _ { 0 }$ .
B) Test statistic: $X ^ { 2 } = 9.870$ . Critical values $= 7.962,26.296 .$ Do not reject $\mathrm { H } _ { 0 }$ .
C) Test statistic: $\mathrm { X } ^ { 2 } = 7.523$ . Critical values $= 9.312,23.542$ . Reject $\mathrm { H } _ { 0 }$ .
D) Test statistic: $\mathrm { X } ^ { 2 } = 9.870$ . Critical values $= 9.312,23.542$ . Do not reject $\mathrm { H } _ { 0 }$ .
