Problem 2

Francesco has measured the speed of sound and has gotten the following measurement result:
v = (345 ± 10) m/s.

He is thinking about the interpretation of his result.

Which statement about his result is true?
His measured speed of sound is 345 m/s.
The speed of sound could be any value between 340 and 350 m/s.
The speed of sound could be any value between 335 and 355 m/s.
He cannot make a statement because he is still a measurement uncertainty.
