Assume the monthly spending in dollars follows a normaldistribution. Test the claim that the mean of monthly spending isno more than $3000at α = 0.05.

Test the claim by following these steps:

  1. State the null and alternative hypotheses and label yournumbers.
  2. 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?
  3. Calculate the test statistic, OR the p-value OR the confidenceinterval.
  4. State the decision rule and make sure to use the criticalvalues, make a decision, and interpret the results.
