Question

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 118 kissing couples, both people in 74 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 118 who do so differs from the expected value by at least as much as what was actually observed? (Round your answer to three decimal places.)

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.)

Explanation / Answer

The statistical software output for this problem is:

One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.66666667
HA : p 0.66666667

Hypothesis test results:

Hence,

a) Probability = 0.362

b) z = -0.91

P - value = 0.3621

Proportion Count Total Sample Prop. Std. Err. Z-Stat P-value p 74 118 0.62711864 0.043396304 -0.91132238 0.3621
