Sound engineers studied factors that might affect the output,in decibels,of a rock concert speaker system.The results of their ANOVA tests are shown (some information is missing).  The F statistic for amplifier was:
A) 9.90. 
B) 10.16. 
C) 5.72. 
D) 4.27.

Quizplus · Accepted Answer

The F statistic for the amplifier is calculated by dividing the mean square for the amplifier by the mean square error. The mean square for the amplifier is 640.18, and the mean square error is 62.99. Therefore, the F statistic would be 640.18/62.99 = 10.16.
