Researchers hypothesized that birds in flight might be better able to avoid accidentally colliding with
windows that were placed at an angle rather than positioned vertically. To test this, windows were
placed at the edge of a forest. Half the windows were vertical and half were tilted at an angle. During
the course of the experiment, 45 birds collided with windows, but only 14 collisions involved the tilted
windows. Does this experiment provide evidence at α = 0.05 that tilting windows significantly reduces
the probability of a bird collision
