4. A static calibration is performed on a pressure-measuring device called a bourdon gage with a nominal range of 0 to 100 psi. The results of this calibration are shown in below Table. a) Plot the data and fit a straight line through them. b) Prepare a deviation plot and estimate the accuracy and repeatability errors, both as a percentage of the output span.
