Final answer:
The Interquartile Range (IQR) for systolic blood pressure in the sample is 19 mm Hg, calculated by subtracting the first quartile (108) from the third quartile (127).
Step-by-step explanation:
The question asks to find the Interquartile Range (IQR) for systolic blood pressure in a sample of 3179 men where the first quartile (Q₁) is 108, the median (second quartile, Q₂) is 116, and the third quartile (Q₃) is 127.
To calculate the IQR, you subtract the first quartile from the third quartile:
IQR = Q₃ - Q₁ = 127 - 108 = 19
Therefore, the IQR for the systolic blood pressure in this sample of men is 19 millimeters of mercury (mm Hg).
