18. A certain population follows a normal distribution with mean $\mu$ and standard deviation $\sigma = 2.5$. You collect data and test the hypotheses
$H_0: \mu = 1, H_a: \mu \neq 1$.
You obtain a p-value of 0.022. Which of the following is true?
(A) A \( 90\% \) confidence interval for \( \mu \) will include the value 1.
(B) A \( 95\% \) confidence interval for \( \mu \) will include the value 1.
(C) A \( 95\% \) confidence interval for \( \mu \) will include the value 0.
(D) A \( 99\% \) confidence interval for \( \mu \) will include the value 1.
(E) A \( 99\% \) confidence interval for \( \mu \) will include the value 0.
