Nine independent measurements are made of the length of a rod. The average of the nine
Chapter 3, Problem 13(choose chapter or problem)
Nine independent measurements are made of the length of a rod. The average of the nine measurements is \(\bar{X}=5.238 \mathrm{~cm}\), and the standard deviation is \(\mathrm{~s}=0.081 \mathrm{~cm}\)
a. Is the uncertainty in the value \(5.238 \mathrm{~cm}\) closest to \(0.009,0.027, \text { or } 0.081 \mathrm{~cm}\) Explain.
b. Another rod is measured once by the same process. The measurement is \(5.423 \mathrm{~cm}\). Is the uncertainty in this value closest to \(0.009,0.027, \text { or } 0.081 \mathrm{~cm}\)? Explain.
