Sound engineers studied factors that might affect the output (in decibels)of a rock concert speaker system.The desired level of significance was α = .05.The results of their ANOVA tests are shown (some information is missing). The most reasonable conclusion at α = .05 about the three sources of variation (amplifier,position,and interaction)would be that their effects are:
A) significant,significant,insignificant.
B) insignificant,significant,significant.
C) very significant,almost significant,insignificant.
