I NEED HELP ASAP! Please and thank you. If you could show a step-by-step, typed out (so it is eligible) I would greatly appreciate it.

APPLY YOUR KNOWLEDGE 21.1 Saving birds from windows. Many birds are injured or killed by ying into windows. It appears that birds don't see windows. Can tilting windows down so that they reect earth rather than sky reduce bird strikes? Researchers placed sh: windows at the edge of a woods: two vertical, two tilted downward 2G degrees, and two tilted downward 40 degrees. During the next four months, there were 53 bird strikes: 31 on the vertical windows, 14 on the Elldegree windows, and E on the ARI-degree windows.3 Does the tilt have an effect? State the null and alternative hypotheses. a. Identify the variable and explain how you know that it is categorical. How many levels does this variable have? b. State the null and alternative hypotheses that are appropriate for the study's ohjecve. 21.1 {a} Window orientation of bird strike, 3 levels. {b} HI}: Pa = 1029 =pm = 1,33, Ha: Hg is not true. APPLY YOUR KNOWLEDGE 21.3 Saving birds from windows, continued. Exercise 21.1 described an experiment designed to figure out whether tilting windows down so that they reflect earth rather than sky can help reduce accidental bird strikes. Calculate the expected counts in each of the three conditions and compute the chi-square statistic. Hide Answer 21.3 Expected counts are all = 53/3 = 17.67.X- = 16.11
