Problem 3E

The article “Supply Voltage Quality in Low-Voltage Industrial Networks of Estonia” (T. Vinnal, K. Janson, et al., Estonian Journal of Engineering, 2012:102–126) presents voltage measurements for a sample of 66 industrial networks in Estonia. Assume the rated voltage for these networks is 232V. The sample mean voltage was 231.7V with a standard deviation of 2.19V. Let μ represent the population mean voltage for these networks.

a. Find the P-value for testing H0 : μ = 232 versus H1 : μ ≠ 232.

b. Either the mean voltage is not equal to 232, or the sample is in the most extreme _________________% of its distribution.
