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 %

uncertainty for 80 mm Hg
uncertainty = 1.667 × 80 / 100
uncertainty = 133.36 / 100
