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.
