Consider the following hypothesis test. H0: 𝜇 ≤ 25 Ha: 𝜇 > 25 A sample of 40 provided a sample mean of 26.3. The population standard deviation is 6. (a) Find the value of the test statistic. (Round your answer to two decimal places.)

Consider the following hypothesis test: \[ \begin{array}{l} H_{0}: \mu \leq 25 \\ H_{\mathrm{a}}: \mu>25 \end{array} \] A sample of 40 provided a sample mean of $26.4 .$ The population standard deviation is $6 .$ a. Compute the value of the test statistic. b. What is the $p$ -value? c. At $\alpha=.01,$ what is your conclusion? d. What is the rejection rule using the critical value? What is your conclusion?
