Problem 2CQQ

Based on the conclusion from Exercise, can electrical appliances be expected to behave the same way when run from the three different power sources? Why or why not? Exercise 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??

Step-by-Step Solution:

Solution 2CQQ Step 1: From the given information, the data is based on the measured voltage amounts from three different sources. In this case, one way analysis of variance is used. Null hypothesis (H ): The null hypothesis states that, the different sources have the 0 same mean measured voltage amounts. Symbolically , H 0 1 = 2 3 Where , = the mean measured voltage amounts of the source where electricity 1 supplied directly to the author’s home. Similarly ,the mean measured voltage amounts of other two sources are and 2 respectively. 3 Alternative hypothesis (H ): t he alternative hypothesis states that, at least one of the 1 sources has the mean measured voltage amounts different from others. Step 2: T he minitab display is From the output the p-value is 0.000 and the F-statistic is 183.01. Then comparing the p-value with the F-statistic ,here the p-value is very smaller than F-statistic. So the null hypothesis is rejected.
