Chapter , Problem 6.43(choose chapter or problem)
A voltmeter is used to measure a known voltage of 100 V. Forty percent of the readings are within 0.5 V of the mean value. Assuming a normal distribution for the error, estimate the standard deviation for the voltmeter. What is the probability that a single reading will have an error greater than 0.75 V?
