given given

blood pressure p = 120 mm Hg

varies pressure Δp = 2 mm Hg

to find out

percent uncertainty

solution

we find here first percentage of uncertainty that is

percent uncertainty = Δp / p × 100%

put here value

percent uncertainty = 2 / 120 × 100%

percent uncertainty = 1.667 %

and

uncertainty for 80 mm Hg

uncertainty = 1.667 × 80 / 100

uncertainty = 133.36 / 100

uncertainty is 1.33 mm Hg
