It is known that roughly 2/3 of all human beings have a dominant right foot or eye. is there also right-sided dominance in kissing behavior? an article reported that in a random sample of 115 kissing couples, both people in 70 of the couples tended to lean more to the right than to the left. (use α = 0.05.)
a) if 2/3 of all kissing couples exhibit this right leaning behavior, what is the probability that the number in a sample of 115 who do so differs from the expected value by at least as much as what was actually observed?
b) does the result of the experiment suggest that the 2/3 figure is implausible for kissing behavior? state and test the hypothesis.
