Data Set 13 in Appendix B lists measured voltage amounts supplied directly to the author?s home. The Central Hudson power supply company states that it has a target power supply of 120 volts. Using those home voltage amounts and assuming that the standard deviation of all such voltage amounts is 0.24 V, test the claim that the mean is 120 volts. Use a 0.01 significance level.

Data Set 13: Voltage Measurements From a Home All measurements are from the author's home. The voltage measure- ments are from the electricity supplied directly to the home, an inde- pendent Generac generator (model PP 5000), and an uninterruptible power supply (APC model CS 350) connected to the home power supply.
