Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results.

Question
![**Blood Pressure Measurement Explanation**
**Blood Pressure Overview:**
Blood pressure is measured using two numbers:
- **Systolic Pressure:** The maximum pressure when the heart is contracting.
- **Diastolic Pressure:** The minimum pressure at the beginning of the heartbeat.
Measurements are given in millimeters of mercury (mmHg). Below is a table displaying blood pressure readings for a sample of seven adults.
**Blood Pressure Readings:**
| Systolic | Diastolic |
|----------|-----------|
| 115 | 83 |
| 133 | 91 |
| 154 | 94 |
| 119 | 69 |
| 123 | 77 |
| 112 | 75 |
| 157 | 103 |
**Statistical Analysis:**
Compute the least-squares regression line for predicting diastolic pressure (\( y \)) from systolic pressure (\( x \)).
- Round all intermediate calculations to at least six decimal places.
- Round the slope and y-intercept to at least four decimal places.
**Regression Line Equation:**
\[ \hat{y} = \_\_\_ \]
**Instructions:**
- Input the calculated values into the provided form to check the answer or submit it as part of an assignment.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F509e8bce-9e19-472b-b32e-290ce2fb93cc%2Fa61059a9-bda1-4bee-97a3-c5e8f4778449%2Fyq1jom9_processed.jpeg&w=3840&q=75)
