Section 3.2 (6 marks)
Your research group is studying problem-solving
behaviour in a population of captive ravens. In your experiment,
ravens are introduced to an observation room one at a time, and
each raven is confronted with a plexiglass puzzle box. The box
contains a reward (a small piece of meat). There is a small hole in
the lid of the box, and a hooked stick has been placed next to the
box. Ravens can solve the task in either of two ways. They can open
the box by manipulating a latch, or they can fish the meat out of
the box using the hooked stick. Among male ravens, 17 used the
latch, 6 used the stick, and 9 did not use either approach and
failed the task. Among female ravens, 5 used the latch, 10 used the
stick, and 9 failed the task. You want to know i) do the sexes
differ in their ability to solve the task, and ii) when they are
able to solve the task, do males and females use different
approaches? Answer each question clearly and concisely, showing
your code (3 marks each). You may omit a supporting
figure.
