Measures of Voltage The author measured voltage amounts from three different sources:

(1) electricity supplied directly to the author’s home, (2) an independent gas-powered Generac generator (model PP 5000), and (3) an uninterruptible power supply (APC model CS 350) connected to the author’s home power supply. The results from analysis of variance are shown below. What is the null hypothesis for this analysis of variance test? What specific result is used in deciding to reject H0 or fail to reject H0? Based on the displayed results, should you reject H0 or fail to reject H0?
