question 50

Multiple Choice

$\mathrm{H}_{\mathrm{a}}: \mu>19, \bar{x}=23.8, \sigma=8, \mathrm{n}=100$ ; 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 less than 1 standard deviation above the claimed mean.
• B) \( \mathrm{H}_{\mathrm{a}} \) is not supported; \( \bar{x} \) is more than 4 standard deriations above the claimed mean.
• C) \( \mathrm{H}_{a} \) is supported; \( \bar{x} \) is less than 1 standard deviation above the claimed mean.
• D) \( \mathrm{H}_{\mathrm{a}} \) is supported; \( \bar{x} \) is more than 4 standard deviations above the claimed mean.
