It is known that roughly 2/3 of all human beings have adominant right foot or eye. Is there also right-sided dominancein kissing behavior? The article Human Behavior:Adult Persistence of Head-Turning Asymmetry(Nature, 2003: 771) reported that in a random sample of124 kissing couples, both people in 80 of the couplestended to lean more to the right than to the left.a. If 2/3 of all kissing couples exhibit this right-leaningbehavior, what is the probability that the number in asample of 124 who do so differs from the expectedvalue by at least as much as what was actuallyobserved?b. Does the result of the experiment suggest that the 2/3figure is implausible for kissing behavior? State andtest the appropriate hypotheses.
