Community college instructors' salaries in one state are very low, so low that educators in that state regularly complain about their compensation. The national mean is $60,156, but instructors from Mississippi claim that the mean in their state is significantly lower. They survey a simple random sample of 33 colleges in the state and calculate a mean salary of $56,842 with a standard deviation of $10,813. Test the instructors' claim at the 0.10 level of significance Step 1 of 3: State the null and alternative hypotheses for the test. Step 2 of 3: Compute the value of the test statistic. Round your answer to three decimal places. Step 3 of 3: Draw a conclusion and interpret the decision
