Use the statement to represent a claim. Write its complement and state which is H_{0} and which is Ha_{.}

µ ≥ 199

**Solution:-**

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 H_{0} and which is H_{a}. A null hypothesis, H_{0}, is a statistical hypothesis that contain a statement of equality. The alternative hypothesis, H_{a}, is the complement of the null hypothesis. It is statement that must be true if H_{0} is false, and it contain a statement of strict inequality. The hypotheses are shown below.

H_{0}:µ≥199

H_{a:}µ<199
