(B) A resistor’s resistance is measured resulting in the resistance values in Table. Assume that the multimeter is unbiased and measurements are independent. Using the values listed in Table, estimate the true value of the resistor’s resistance, Rtrue, and calculate the measurement’s standard deviation, sR.
