In the Focus Problem at the beginning of this chapter, a study was described comparing the hatch
Question:
(a) Find a point estimate 1 for p1, the proportion of eggs that hatch in group I nesting boxes. Find a 95% confidence interval for p1.
(b) Find a point estimate 2 for p2, the proportion of eggs that hatch in group II nesting boxes. Find a 95% confidence interval for p2.
(c) Find a 95% confidence interval for p1 - p2. Does the interval indicate that the proportion of eggs hatched from group I nesting boxes is higher than, lower than, or equal to the proportion of eggs hatched from group II nesting boxes?
(d) What conclusions about placement of nesting boxes can be drawn? In the article discussed in the Focus Problem, additional concerns are raised about the higher cost of placing and maintaining group I nesting boxes. Also at issue is the cost efficiency per successful wood duck hatch.
