A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation.

**Blood Pressure Variation Analysis** A sample of blood pressure measurements is taken for a group of adults, with values (mm Hg) matched for 10 subjects, each having systolic and diastolic measurements. The goal is to calculate the coefficient of variation for both and compare the results. - **Systolic Measurements:** 120, 129, 158, 96, 123, 115, 135, 125, 118 - **Diastolic Measurements:** 82, 75, 72, 52, 89, 99, 60, 74, 70, 80 **Calculation Steps:** 1. **Coefficient of Variation for Systolic Measurements:** - The user is required to input the calculated percentage. - Prompt: "Type an integer or decimal rounded to one decimal place as needed." 2. **Coefficient of Variation for Diastolic Measurements:** - The user is required to input the calculated percentage. - Prompt: "Type an integer or decimal rounded to one decimal place as needed." 3. **Comparison of Variation:** - Users can select one of the following comparisons for the systolic vs. diastolic variation: - about the same as - significantly more than - significantly less than **Interactive Element:** A drop-down menu allows users to choose how the systolic measurements vary compared to the diastolic measurements. **Note:** Accurate calculation and selection based on the coefficients of variation are crucial for understanding blood pressure variability.

Expert Solution
Step 1

Use EXCEL Procedure for finding the values of systolic and Diastolic.

 

Follow the instruction to obtain the values of mean and SD:

 

  1. Open EXCEL
  2. Go to Data>Data Analysis.
  3. Choose Descriptive Statistics.
  4. Enter the input range as $A$1:$A$11.
  5. Check the Labels in the first row.
  6. Check the option Summary statistics
  7. Click OK.

 

EXCEL output:

 

Statistics homework question answer, step 1, image 1

From the EXCEL output,

 

The values of mean and SD for systolic is,

 

The value of Mean is 127.5

 

The value of standard deviation is 18.6264
