Question

A student can hold her breath for 94 seconds if another student records that the time she can hold her breath is 92 seconds, what is the percent error in this measurement?

Answer 1

Answer: -2.13%

Step-by-step explanation:

I will assume that the correct time is 94 seconds, since it is stated as a fact. The measured time of 92 seconds is -2 seonds from the actual. That gives a percent error of:

[(Measured-Actual)/Actual] or (-2/94) or -2.13%
