Dogs Ignore an Unreliable Person
A study¹ investigated whether dogs change their behavior depending on whether a person displays reliable or unreliable behavior.
Dogs were shown two containers, one empty and one containing a dog biscuit. An experimenter pointed to one of the two containers.
If the experimenter pointed to the container with the treat on the first trial, 16 of 26 dogs followed the experimenter's cue on the
second trial. However, if the experimenter misled the dog on the first trial, only 7 of 26 dogs followed the cue on the second trial. Test
to see if the proportion following the cue is different depending on whether the person exhibited reliable or unreliable behavior. The
standard error for the difference in proportions is 0.138. Use a 5% significance level.
Let group 1 be the dogs to follow a cue from a person who is reliable and let group 2 be the dogs to follow a cue from a person who is
unreliable.…
