Question
Transcribed Image Text:**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.
