6.62 Do Babies Understand Probability? Can babies reason probabilistically? A studylz investigates this by showing ten- to twelve-month-old infants two jars of lollipopshaped objects colored pink or black. Each infant rst crawled or walked to whichever color they wanted, determining their \"preferred\" color. They were then given the choice between two jars that had the same number of preferred objects, but that differed in their probability of getting the preferred color; each jar had 12 in the preferred color and either 4 or 36 in the other color. Babies choosing randomly or based on the absolute number of their preferred color would choose equally between the two jars, while babies understanding probability would more often choose the jar with the higher proportion of their preferred color. Of the 24 infants studied, 18 chose the jar with the higher proportion of their preferred color. Are infants more likely to choose the jar with the higher proportion of their preferred color? a. State the null and alternative hypotheses. b. Give the relevant sample statistic, using correct notation. c. Which of the following should be used to calculate a pvalue for this dataset? A randomization test, a test using the normal distribution, or either one? Why? (1. Find a p-value using a method appropriate for this data situation. e. Make a conclusion in context, using a = 0.05
