You may need to use the appropriate appendix table or technology to answer this question. (a) Give the null and the alternative hypotheses (in hours). (Enter \( != \) for \( \neq \) as needed.) \[ \begin{array}{l} H_{0}: \quad \mu=86 \\ H_{\mathrm{a}}: \end{array} \] (b) Compute the test statistic. (Round your answer to two decimal places.) (c) At the \( 1 \% \) level of significance using the critical value approach, test management's belief. State the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic \( \leq \) test statistic \( \geq \) State your conclusion. Reject \( H_{0} \). There is sufficient evidence to support the management's belief. Reject \( H_{0} \). There is insufficient evidence to support the management's belief. Do not reject \( H_{0} \). There is sufficient evidence to support the management's belief. Do not reject \( H_{0} \). There is insufficient evidence to support the management's belief. (d) What is the \( p \)-value associated with the sample results?
