Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded? a. The test statistic, t, is (Round to two decimal places as needed.) b. The P-value is (Round to three decimal places as needed

Question
Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test for a difference between the measurements from the two arms. What can be concluded?
a. The test statistic, t, is
(Round to two decimal places as needed.)
b. The P-value is
(Round to three decimal places as needed.)
Transcribed Image Text:**Data Analysis: Blood Pressure Measurements**
The table below compares the blood pressure readings taken from the right and left arms over a series of measurements. Observing such variations can be crucial in diagnosing cardiovascular conditions.
- **Right Arm Measurements:**
- 150 mmHg
- 139 mmHg
- 128 mmHg
- 135 mmHg
- 132 mmHg
- **Left Arm Measurements:**
- 178 mmHg
- 177 mmHg
- 177 mmHg
- 147 mmHg
- 136 mmHg
**Analysis:**
This data set suggests that there may be a noticeable difference in blood pressure readings between the right and left arms, with the left arm consistently showing higher values. Such differences can sometimes indicate underlying vascular issues, and further medical investigation is often recommended to explore these findings.
**Educational Note:**
When recording blood pressure, it's important to measure both arms for an accurate assessment, as significant differences might necessitate further evaluation for conditions such as peripheral artery disease.
