.D. Power and Associates’ 2004 Wireless Call Quality Performance Study provided most carriers with something to brag about, as four of the six nationwide operators posted high scores for at least one of the six regions the marketing firm included in the study.

How can you call this a sufficiently large enough group to decide for such a large number of people?

ok, for some reason that got cut off at the hip.
