A simple random sample of size \( n=15 \) is drawn from a population that is normally distributed. The sample mean is found to be \( \bar{x}=27.4 \) and the sample standard deviation is found to be \( s=6.3 \). Determine if the population mean is different from 24 at the \( \alpha=0.01 \) level of significance. Complete parts (a) through ( \( d \) ) below. (c) State the conclusion for the test. A. Reject \( H_{0} \) because the P-value is greater than the \( \alpha=0.01 \) level of significance. B. Reject \( H_{0} \) because the P-value is less than the \( \alpha=0.01 \) level of significance. Do not reject \( H_{0} \) because the \( P \)-value is less than the \( \alpha=0.01 \) level of significance. Do not reject \( H_{0} \) because the \( P \)-value is greater than the \( \alpha=0.01 \) level of significance.
