changes, but lately you have been getting some customer complaints that it takes too long to g oil change, You take a random sample of 36 customers and time how long (in minutes) the customer must wait for their oil change. The results are in the table below. \begin{tabular}{|l|l|l|l|l|l|} \hline 42 & 29 & 19 & 11 & 10 & 27 \\ \hline 41 & 27 & 22 & 26 & 28 & 32 \\ \hline 17 & 15 & 25 & 35 & 31 & 22 \\ \hline 13 & 31 & 17 & 37 & 33 & 25 \\ \hline 18 & 24 & 28 & 21 & 40 & 19 \\ \hline 33 & 30 & 14 & 23 & 22 & 10 \\ \hline \end{tabular} (data from hittp:/lorg.elon.edu/econ/sac/Descriptive.htm) In the questions below, you will perform a hypothesis test on the claim that the mean wait time is less than 30 minutes at a significance level of 0.01 . 1. Write the null and alternative hypothesis. (Make sure to label which is which and use the correct symbol $ p $ or $ \mu $ ) \[ \begin{array}{l} H_{0}: U \geq 30 \\ H_{a}: V<30 \end{array} \] 2. Use your calculator to find the Test Statistic and p-value. Label each accordingly. Round to 4 decimal places. \[ T=\frac{24.5-30}{\frac{5}{\sqrt{36}}} \] 3. Use the t-distribution table on the last page of your formula chart to find the critical value.
