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 136 kissing couples, both people in 88 of the couples tended to lean more to the right than to the left. (Use a = 0.05.) in USE SALT (a) If 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample of 136 who do so differs from the expected value by at least as much as what was actually observed? (Round your answer to four decimal places.) 0.4960 x (b) Does the result of the experiment suggest that the 2/3 figure is implausible for kissing behavior? State the appropriate null and alternative hypotheses. O Ho: p = 2/3 Hap # 2/3 O Ho: P = 2/3 Hp > 2/3 O Ho: p = 2/3 Haip 5 2/3 O Ho: p = 2/3 He: p < 2/3 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = P-value = 0.6198 X
