Distinguish helping and hindering among infants, continued Fourteen of the 16 infants in the Yale study elected to play with a toy resembling the helpful figure as opposed to one resembling the hindering figure. Is this convincing evidence that infants tend to prefer the helpful figure? Use the Random Numbers web app on the book’s website to investigate the approximate likelihood of the observed results of 14 out of 16 infants choosing the helpful figure, if in fact infants are indifferent between the two figures. To perform a simulation with this app, click on the Coin Flips tab and set the number of flips to generate equal to 16. Click on Simulate and determine the number of heads in the generated sequence. This represents the number of times the child selects the helpful toy if they choose at random.

Repeat this simulation for a total of 10 simulations.

Out of the 10 simulations, how often did you obtain 14 or more heads out of 16 tosses? Are your results convincing evidence that infants actually tend to exhibit a preference?
