Four students want to know the most accurate way to measure the speed of a wave. The method their professor uses has a percent error of 3.68%. Each student tests a different method and writes the result in the chart below.


If the accepted value of a wave is 121 m/s, who has the most accurate method of measuring the speed of a wave?

the professor
Erin
Jean-Claude
Suresh

I don't see the students' measured values in your message — can you paste the chart or give Erin's, Jean-Claude's, and Suresh's measured speeds?

Meanwhile, here's how I'll determine who is most accurate: compute each percent error with

percent error = (|measured − accepted| / accepted) × 100%

with accepted = 121 m/s. For example, the professor's percent error 3.68% corresponds to an absolute error of 0.0368×121 = 4.4528 m/s, so the professor's measurement would be either about 116.55 m/s or 125.45 m/s (depending on whether it was low or high). Once you give the three students' measured values I will calculate each percent error and identify the smallest one (most accurate).
