You have been working with a marine biologist on a trip from Baltimore through the Chesapeake Bay,to the open ocean,and back to test salinity levels and the kinds of plankton that live in each sampled area.The marine biologist is very nearsighted and she cannot see more than a few feet without the eyeglasses she lost two days ago when out on the open ocean.She arises one morning late in the trip,with no idea where the ship is.But after an hour of hearing you report salinity readings that vary by as much as 1 percent,she says,"So,we're in the Chesapeake Bay?" How did she (correctly)make that conclusion based on the information provided?
