Six different second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic readings (in mmHg) are listed below. Finc range, variance, and standard deviation for the given sample data. If the subject's blood pressure remains constant and the medical students correctly apply the same measurement technique, what should be the value of the standard deviation? 143 139 143 150 132 145 D What should be the value of the standard deviation? A. Ideally, the standard deviation would be one because this is the lowest standard deviation that can be achieved. O B. Ideally, the standard deviation would be zero because all the measurements should be the same. C. Ideally, the standard deviation would be one because all the measurements should be the same. D. There is no way to tell what the standard deviation should be.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

![**Blood Pressure Measurement and Statistical Analysis**
Six different second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic readings (in mmHg) are listed below. Find the range, variance, and standard deviation for the given sample data. If the subject's blood pressure remains constant and the medical students correctly apply the same measurement technique, what should be the value of the standard deviation?
**Sample Readings (mmHg):**
143, 139, 143, 150, 132, 145
**Questions:**
1. **Range = [ ] mmHg**
2. **Sample variance = [ ] mmHg² (Round to the nearest tenth as needed.)**
3. **Sample standard deviation = [ ] mmHg (Round to the nearest tenth as needed.)**
**What should be the value of the standard deviation?**
A. Ideally, the standard deviation would be zero because this is the lowest standard deviation that can be achieved.

In this task, there are no graphs or diagrams presented, only numerical data and textual instructions. To solve, follow these steps:
1. **Range Calculation**:
- The range is the difference between the highest and lowest values in the sample.
- Highest value: 150 mmHg
- Lowest value: 132 mmHg
- Range = 150 mmHg - 132 mmHg = 18 mmHg
2. **Sample Variance Calculation**:
- Variance measures the dispersion of the data points. It is calculated by taking the average of the squared differences from the mean.
3. **Sample Standard Deviation Calculation**:
- The standard deviation is the square root of the variance. It provides a measure of the amount of variation or dispersion in the sample data.
For accurate answers, all intermediate calculations should be noted down and rounded as specified to the nearest tenth.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F404f3d89-f0b1-449e-ae9e-190d04b3c0e1%2Fc5167e73-e077-4325-868d-62f64161b6cd%2Fem0q0z7.jpeg&w=3840&q=75)
