Oil spill impact on seabirds. Refer to the Journal of ^ Agricultural, Biological, and Environmental Statistics (Sept. 2000) study of the impact of the Exxon Valdez tanker oil spill on the seabird population in Prince William Sound, Alaska, Recall that data were collected on 96 shoreline locations (called transects), and it was determined whether or not the transect was in an oiled area. The data are stored in the file called EVOS. From the data, estimate the probability that a randomly selected transect in Prince William Sound is contaminated with oil.

Oil spill impact on seabirds. The Journal of Agricultural, Biological, and Environmental Statistics (Sept. 2000) published a study on the impact of the Exxon Valdez tanker oil spill on the seabird population in Prince William Sound, Alaska. A subset of the data analyzed is stored in the EVOS file. Data were collected on 96 shoreline locations (called transects) of constant width, but variable length. For each transect, the number of seabirds found is recorded, as are the length (in kilometers) of the transect and whether or not the transect was in an oiled area. (The first five and last five observations in the EVOS file are listed in the accompanying table.)
