Question: Many voltage ( > 1 0 , 0 0 0 ) readings are taken from a power supply. The sample mean voltage reading is V

Many voltage (>10,000) readings are taken from a power supply. The sample mean voltage reading is V =13.2 V. The sample standard deviation of all the readings is 0.1 V. We assume that the errors in the readings are purely random. Calculate the tolerance in voltage measurement to 97% confidence level.
