Defects in randomly inspected led displays

Reference no: EM13240665

Two manufacturing facilities produce 1280 × 1024 LED (light-emitting diode) displays. Twelve displays are chosen at random from each lab, and the number of bad pixels is noted for each display.

Research question: At α = .05, do the medians differ?
