(a) An instrument is calibrated in an environment at 20C and the following output

readings y are obtained for various input values x:

y 13.1 26.2 39.3 52.4 65.5 78.6

x 5 10 15 20 25 30

Determine the measurement sensitivity, expressed as the ratio y/x.

(b) When the instrument is subsequently used in an environment at 50C, the

inputeoutput characteristic changes to the following:

y 14.7 29.4 44.1 58.8 73.5 88.2

x 5 10 15 20 25 30

Determine the new measurement sensitivity. Then determine the sensitivity drift

due to the change in ambient temperature of 30C.
