Can Domestic Dogs Understand Human Body Cues Such as Leaning

Short Answer

Can domestic dogs understand human body cues such as leaning? The experimenter leaned toward one of two objects and recorded whether or not the dog being tested correctly chose the object indicated. A four-year-old male beagle named Augie participated in this study. He chose the correct object 8 out of 10 times when the experimenter leaned towards the correct object. Shown below is a simulation of 1000 sample proportions under the assumption that the long-run probability that Augie chooses correct is 0.50.
-Suppose that we repeated the same study with Augie, and this time he chose the correct object 16 out of 20 times. Conjecture how, if at all, the center and the width of a 2SD 95% confidence interval would change with these data, compared to the original 8 out of 10 times.
The center of the confidence interval would ______ (1).
The width of the confidence interval would ______ (2).
Drop-down options for (1) and (2):
•increase
•decrease
•remain the same
