question 13

Multiple Choice

$\mathrm { H } _ { \mathrm { a } } : \mu > 19.9 , \bar { x } = 23.1 , \sigma = 8 , \mathrm { n } = 100$ . Without computing a $\mathrm { P }$ -value, determine whether the alternate hypothesis is supported and give a reason for your conclusion.

• A) \(\mathrm { H } _ { \mathrm { a } }\) is not supported : \(\bar { x }\) is more than 3 standard deviations above the claimed mean.
• B) \(\mathrm { H } _ { \mathrm { a } }\) is not supported: \(\bar { x }\) is less than 1 standard deviation above the claimed mean.
• C) \(\mathrm { H } _ { \mathrm { a } }\) is supported ; \(\bar { x }\) is more than 3 standard deviations above the claimed mean.
• D) \(\mathrm { H } _ { \mathrm { a } }\) is supported : \(\bar { x }\) is less than 1 standard deviation above the claimed mean.
