An infant's pulse rate is measured to be 130±5130±5 beats/min. What is the percent uncertainty in this measurement?

A person measures his or her heart rate by counting the number of beats in 30s30s . If 40±140±1 beats are counted in 30.0±0.5s30.0±0.5s , what is the heart rate and its uncertainty in beats per minute?

(a) A person's blood pressure is measured to be 120 ± 2 mm Hg120 ± 2 mm Hg . What is its percent uncertainty? (b) Assuming the same percent uncertainty, what is the uncertainty in a blood pressure measurement of 80 mm Hg?

(a) If your speedometer has an uncertainty of 2.0km/h2.0km/h at a speed of 90km/h90km/h , what is the percent uncertainty? (b) If it has the same percent uncertainty when it reads 60km/h60km/h , what is the range of speeds you could be going?

Here is some data of a few patient's pulse measurement: 1) Find the mean of a variable "pulse rate". Find the standard deviation of a variable "pulse rate" Use the correct symbol and choose the correct formula from the list. Plug in numbers, you don't have actually to calculate it. The correct answer is 14.2227 bpm. What would be unusually high and unusually low pulse rate?

In an experiment to determine the acceleration of free fall g, the time t taken for a ball to fallthrough distance s is measured. The percentage uncertainty in the measurement of s is 2%. Thepercentage uncertainty in the measurement of t is 3%.The value of g is determined using the equation shown.22tsg What is the percentage uncertainty in the calculated value of g?A 1% B 5% C 8% D 11%
