random sample of 136 kissing couples, both people in 84 of the couples tended to lean more to the right than to the left. (Use ? = 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 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.)

Question
random sample of 136 kissing couples, both people in 84 of the couples tended to lean more to the right than to the left. (Use ? = 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 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.)
(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.
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.)
(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.
H0: p = 2/3
Ha: p > 2/3H0: p = 2/3
Ha: p ≤ 2/3 H0: p = 2/3
Ha: p < 2/3H0: p = 2/3
Ha: p ≠ 2/3
Ha: p > 2/3H0: p = 2/3
Ha: p ≤ 2/3 H0: p = 2/3
Ha: p < 2/3H0: p = 2/3
Ha: 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.)
