(Answered) A a persons blood pressure is measured to be 112 plusmn 5

Academics

(a) A person's blood pressure is measured to be 112 ± 5 mm Hg. What is its percent uncertainty? (Note that percent uncertainties should be reported to two significant figures.) WebAssign will check your answer for the correct number of 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.) WebAssign will check your answer for the correct number of significant figures. mm Hg
