Question
**Blood Pressure Overview**

Blood pressure is measured in two numbers: the systolic and diastolic pressures. 

- **Systolic Pressure:** This is the maximum pressure taken when the heart is contracting.
- **Diastolic Pressure:** This is the minimum pressure taken at the beginning of the heartbeat.

The table below shows blood pressure measurements, in millimeters of mercury, for a sample of 8 adults:

| Systolic | Diastolic |
|----------|-----------|
| 126      | 88        |
| 104      | 86        |
| 103      | 80        |
| 110      | 80        |
| 122      | 71        |
| 117      | 88        |
| 130      | 75        |
| 118      | 69        |

**Task**

Compute the least-squares regression line for predicting diastolic pressure (\(y\)) from systolic pressure (\(x\)). Round the intermediate calculations to at least six decimal places and round the slope and y-intercept values to at least four decimal places.

**Regression Line Equation**

Write the equation \(\hat{y} = \) and calculate the necessary coefficients to complete the regression model.

**Notes**

- The "Send data to Excel" feature can assist in the data analysis process.
- Ensure calculations are precise to facilitate accurate predictions.

**Additional Options**

- You can save your progress for later or submit the assignment when ready.
