Question
**Claim:** The mean systolic blood pressure of all healthy adults is less than 126 mm Hg. Sample data: For 299 healthy adults, the mean systolic blood pressure level is 122.73 mm Hg and the standard deviation is 15.31 mm Hg. Complete parts (a) and (b).

a. **Express the original claim in symbolic form. Let the parameter represent a value with respect to systolic blood pressure of a healthy adult.**

\[ \mu < 126 \]

(Type an integer or a decimal. Do not round.)

b. **Identify the null and alternative hypotheses.**

- \[ H_0: \mu = 126 \]
- \[ H_1: \mu < 126 \]

(Type integers or decimals. Do not round.)

This image is a part of a statistical problem-solving exercise involving hypotheses about the mean systolic blood pressure of a group of healthy adults. The aim is to determine whether sample data supports the claim of a mean value lower than a specified threshold using hypothesis testing.
