Question

In Chapter 9, we described a study showing that newborn infants spend more time looking at attractive faces when they are shown together with less attractive faces (Slater, et al., 1998). In the study, a pair of faces is shown on a screen and the researchers record the amount of time the baby spends looking at each face. In a sample of n = 40 infants, suppose that 26 spent the majority of their time looking at the more attractive face and only 14 spent the majority of time looking at the unattractive face. Is this result significantly different from what would be expected if there were no preference between the two faces? Test with a = .05.
