Chapter 1: Q10PE (page 11)

An infant鈥檚 pulse rate is measured to be 130卤5beats/min. What is the percent uncertainty in this measurement?

Short Answer

Expert verified

The percentage uncertainty in the given case is 3.846%.

Step by step solution

01

Definition of percentage uncertainty

Percentage uncertainty implies the percentage of uncertainty in a given situation. Since it is a percentage, it has no units.

02

Calculation of percentage uncertainty

Consider the given data as stated below.

An infant鈥檚 pulse rate is_ -A = 130 beats/min.

The uncertainty, 未础=5beats/min.

The percentage of uncertainty is defined as follows:

未础%=未础A脳100%

Substitute 5 beats/min for 未础and 130 beats/min for Ain the above equation.

未础%=5beats/min130beats/min脳100%=3.846%

03

Conclusion

Hence, the percentage uncertainty in the given case is 3.846%.
