Students have asked these similar questions

(a) A person's blood pressure is measured to be 104 ± 2 mm Hg. What is its percent uncertainty? (Note that percent uncertainties should be reported to two significant figures.) % (b) Assuming the same percent uncertainty, what is the uncertainty in a blood pressure measurement of 80 mm Hg? (Note that uncertainties should be reported to one significant figure.). mm Hg

(a) A person’s blood pressure is measured to be 120+2 mm Hg. What is its percent uncertainty? (b) Assuming the same percent uncertainty, what is theuncertainty in a blood pressure measurement of 80mm Hg?

A person's blood pressure is measured to be: 115 ± 7 mm Hg. What is its percent uncertainty? (Express your answer to the correct number of significant figures and proper units. Use unrounded values in your calculations.)
