Question #39 An engineer is testing a multimeter against a set of reference conductive metal plates with known true voltage values. She takes repeated measurements of the reference values and uses her results in a gage linearity study. The results include this scatterplot of biases for each reference value and the regression line through the points. What can we conclude from this plot? Reference Value A) Linearity is low; bias is fairly consistent over the range of reference values. B) Linearity is low; bias changes over the range of reference values. C) Linearity is high; bias is fairly consistent over the range of reference values. D) Linearity is high; bias changes over the range of reference values
