Chapter 0, Problem 23.15(choose chapter or problem)
Many birds are injured or killed by flying intowindows. It appears that birds dont see windows. Can tilting windows down sothat they reflect earth rather than sky reduce bird strikes? Place six windows at theedge of a woods: two vertical, two tilted 20 degrees, and two tilted 40 degrees.During the next four months, there were 53 bird strikes, 31 on the verticalwindow, 14 on the 20-degree window, and 8 on the 40-degree window.9 If the tilthas no effect, we expect strikes on all three windows to have equal probability.Test this null hypothesis. What do you conclude?
