Explanation / Answer

slope of current versus voltage is

(.002857 ± 0.0003265) A/V.

from ohms law V=iR

1/R=i/V = A/V

1/R=(.002857 ± 0.0003265)A/V

R = 1/((.002857 ± 0.0003265)

R = (0.002857)^-1 = 350.01

(0.002857+ 0.0003265)^-1 = 314.119

(0.002857- 0.0003265)^-1 =395.178

difference in slope is

395.178-314.119=81.05

answer : R = 350.01±81.05 ohm
