In the Focus Problem at the beginning of this chapter, a study was described comparing the hatch ratios of wood duck
nesting boxes. Group I nesting boxes were well separated from each other and well hidden by available brush. There were a
total of 491 eggs in group I boxes, of which a field count showed about 276 hatched. Group II nesting boxes were placed in
highly visible locations and grouped closely together. There were a total of 780 eggs in group II boxes, of which a field count
showed about 278 hatched.
(a) Find a point estimate p, for p1, the proportion of eggs that hatch in group I nest box placements. (Round your
