Question

A single DMM with accuracy ±(0.5% of reading + 3 digits) is used to measure a nominally constant voltage within a circuit ten times. The following readings are obtained: (a)

Estimate the 95% confidence interval for the voltage. Clearly state your assumptions and justify your answer. (b) Does having ten measurements substantially improve the confidence interval of your estimate? Clearly state your assumptions and justify your answer.
