Problem 971

Use the given statement to represent a claim. Write its complement and state which is Ho 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 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 contains a statement of equality. The alternative hypothesis, Ha, is the complement of the null hypothesis. It is a statement that must be true if H0 is false, and it contains a statement of strict inequality. The hypotheses are shown below.

H0: µ ≥ 199

Ha: µ < 199
