Question
![### Estimating Average Resting Heart Rate
#### Overview:
A normal resting heart rate for adults ranges from about 60 to 100 beats per minute (BPM). A doctor aims to estimate the average heart rate for one of her patients. The patient is instructed to measure their resting heart rate twice a day for one week. Listed below are the collected measurements. Assume the distribution of all heart rate measurements from this patient is approximately normally distributed.
#### Heart Rate Measurements:
| 93 | 91 |
|----|----|
| 87 | 86 |
| 81 | 84 |
| 85 | 85 |
| 80 | 93 |
| 87 | 85 |
| 80 | 88 |
#### Task:
1. **Determine the point estimate (\(\bar{x}\)) and sample standard deviation (\(s\)):**
- Round the solutions to four decimal places if necessary.
- \(\bar{x} = \)
- \(s = \)
2. **Using a 95% confidence level:**
- Determine the margin of error (\(E\)) and a confidence interval for the average resting heart rate of this patient.
- Report the confidence interval using interval notation.
- Round solutions to two decimal places if necessary.
- The margin of error is given by \(E = \).
- A 95% confidence interval is given by \([ \quad , \quad ]\).
