Essay

One difficulty in measuring the nesting success of birds is that the researchers mustcount the number of eggs in the nest, which is disturbing to the parents. Even thoughthe researcher does not harm the birds, the flight of the bird might alert predators tothe presence of a nest. To see if researcher activity might degrade nesting success,the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four ofthese nests failed (meaning the parent abandoned the nest.)

Assuming that it is reasonable to regard the 102 nests in the sample as representativeof the population of nests for which the eggs have been counted, construct andinterpret a 95% confidence interval for the proportion of nests that have eggs countedthat are then abandoned.
