Explanation / Answer

Part a)

% uncertainity = (3/39)*100=7.69%

Part b)

minimum value of beat rate can be determined by considering minimum values of beats and maximum amount of time

minimum number of beats = 39-3=36

maximum amount of time = 30+0.5=30.5 seconds'

minimum number of beats per minute=(36/30.5)*60=70.8 beats per minute

Part c)

maximum value of beat rate can be determined by considering maximum values of beats and minimum amount of time

maximum number of beats = 39+3=42

minimum amount of time = 30-0.5=29.5 seconds'

minimum number of beats per minute=(42/29.5)*60=85.4 beats per minute
