Imagine being lost at sea, bobbing around in an orange life jacket. The Coast Guard sends out two kinds of observers to spot you, fellow humans and pigeons. All observers are successful; the search time for each is given in the table in minutes. Decide on a one- or two-tailed test, analyze the data, and write a conclusion.
