Question

If the bathroom scale at home always measures a person's weight to the nearest 0.2 pounds AND always weighs them 1.8 pounds heavier than they actually are: 3ci) Is this a random or systematic error on the part of the scale? 3cii) Can this error be corrected so that every time you weigh yourself you know the correct weight? If so, how? If not, why not? Assume that you CANNOT alter anything on the scale itself. You cannot physically change anything on the scale. 3ciii) What is the precision of the measuring instrument, in this case, the scale?
