Questions about making an inference based on a distribution of sample proportions (Module 18) 3) In the Yale experiment, 14 out of 16 infants chose the helper toy. This a sample proportion of 0.875. a) Is 14 out of 16 unusual in a random sample if we assume p=0.5? Explain how you know. b) What is the probability that in a random sample of 16 infants, 14 or more will choose the helper toy? Explain how you determined the probability.c) The Yale researchers claim that infants recognize, and make judgments about, other individuals based on how they interact with each other. To show this, their experiment must produce strong evidence that the infants are not arbitrarily picking one toy over the other. Does their experiment provide strong evidence in support of their claim that infants have a preference for the helper? Why or why not
