An understanding of choices of habitat is an important element in understanding the biology and ecology of birds. One aspect of habitat choice is the pattern of preferred vertical height when feeding in forests. In a study of small birds in an old-growth forest in the Pacific Northwest, researchers, suspended from a giant crane, observed the landings of Golden-crowned kinglets (Regulus strapa). They found that 78 of the 163 landings were in the "mid" height region of trees, 21-40 meters above ground.
A) Compute an estimate of the population proportion of all landings of these kinglets that are in the 21-40 meter height range.
B) Based on the data above, what is the margin of error of \hat{p} ?
