Question 167438 • Probability and Statistics with Applications Honors Sem-2-FL-1210300 (2024-2025)
A P-value is calculated assuming the null hypothesis is true. Here, the null mean salary is $48,553, and the observed sample mean is $49,021; the P-value of 1.24% is the probability of getting a sample mean of $49,021 or higher by chance alone under that assumption. It does not give the probability that the null hypothesis itself is true, so D is correct.
