The voltage in a circuit is 115 volts. A particular technique
for measuring the voltage gives readings which are normally
distributed with mean μ=115 volts and standard deviation 5 volts.
Show that the average of four readings has smaller probability of
differing from the true value by 3 volts than an individual
reading. Hence show that average of several measurement of the same
thing is always more accurate than an individual measurement.
