Toys. Researchers presented young children with a choice between two toy characters who were offering stickers. One character was described as mean, and the other was described as nice. The mean character offered two stickers, and the nice character offered one sticker. Researchers wanted to investigate whether infants would tend to select the nice character over the mean character, despite receiving fewer stickers. They found that 16 of the 20 children in the study selected the nice character.

a) (3 pts) Describe (in words) the null hypothesis in this study.

b) (3 pts) Suppose that you were to conduct a simulation analysis of this study to investigate whether the observed result provides strong evidence that children genuinely prefer the nice character with one sticker over the mean one with two stickers. Indicate what you would enter for the following three inputs: ? i) Probability of success ? ii) Sample size ? iii) Number of samples.
