Problem 38E

Blood pressure values are often reported to the nearest 5 mmHg (100, 105, 110, etc.). Suppose the actual blood pressure values for nine randomly selected individuals are a. What is the median of the reported blood pressure values? b. Suppose the blood pressure of the second individual is 127.6 rather than 127.4 (a small change in a single value). How does this affect the median of the reported values? What does this say about the sensitivity of the median to rounding or grouping in the data?

Step-by-Step Solution:
Step 1 of 3

Problem 38E Answer: Step1: We have Blood pressure values are often reported to the nearest 5 mmHg (100, 105, 110, etc.). Suppose the actual blood pressure values for nine randomly selected individuals are x 118.6 127.4 138.4 130 113.7 122 108.3 131.5 133.2 We need to find, a. What is the median of the reported blood pressure values b. Suppose the blood pressure of the second individual is 127.6 rather than 127.4 (a small change in a single value)....
