You repeat the exact same measurement 30 times. How would you calculate the interval for 99% certainty in your given value? A certain sensor outputs a voltage in response to a change in displacement. The output voltage ranges from 0 to +5V over an input displacement range of 0 to 10cm. If the resolution of the voltmeter is 0.01V, what is the smallest corresponding displacement you can measure using the sensor and the voltmeter? One half of this value is the resolution uncertainty of your voltmeter-sensor combination.
