Problem

A set of experimental readings for a conductor at constant temperature is given below: $

\begin{array}{cc} V\,(\text{V}) & 2.0 \quad 4.1 \quad 6.2 \quad 8.0\\ I\,(\text{A}) & 0.39 \quad 0.83 \quad 1.20 \quad 1.63 \end{array}

$ Considering the small measurement errors in the data, which of the following is the best estimate of the conductor’s resistance? a)

4\,\Omega

15\,\Omega

5\,\Omega

10\,\Omega
