If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is  μ<=80.

The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.

  • The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.                                                 
  • It always contains = , ≤ , ≥ signs.
  • The results will be examined using a one-tailed hypothesis test.

       Hence, μ<=80
