A pressure measuring system outputs a voltage that is proportional to pressure. It is calibrated against a transducer standard (certified error: within
0.5 psi) over its 0–100-psi range with the results given below. The voltage is measured with a voltmeter (instrument error: within
10 µV; resolution: 1 µV). The engineer intending to use this system estimates that installation effects can cause the indicated pressure to be off by another
 0.5 psi. Estimate the expanded uncertainty at 95% confidence in using the system based on the known information.
