Test the claim by following these steps:
- State the null and alternative hypotheses and label yournumbers.
- Describe your test, is it an upper z (or t) tailed-test, alower z (or t) tailed-test, or a two-tailed z (or t) test?
- Calculate the test statistic, OR the p-value OR the confidenceinterval.
- State the decision rule and make sure to use the criticalvalues, make a decision, and interpret the results.
