Use the statement to represent a claim. Write its complement and state which is H0 and which is Ha.
µ ≥ 199
Begin by finding the complement of the claim. The complement of a claim is the statement that must be true when the claim is false. The complement of the claim is shown below.
µ < 199
now determine which is H0 and which is Ha. A null hypothesis, H0, is a statistical hypothesis that contain a statement of equality. The alternative hypothesis, Ha, is the complement of the null hypothesis. It is statement that must be true if H0 is false, and it contain a statement of strict inequality. The hypotheses are shown below.
