For each of the steps below, explain your work in words, symbols, and pictures.

  1. Write the null and alternative hypotheses in words and symbols.

  2. Check the conditions necessary to use the Central Limit Theorem.

  3. Select an alpha level and use it to find the critical values.

  4. Find your test statistic and compare it to the critical values.

  5. Compute the p-value of your test statistic and compare it to alpha.

  6. Describe what the p-value measures in this hypothesis test.

  7. Make a decision about the null hypothesis.

  8. Interpret that decision.
