Question
Can you pls explain step by step how were the correct answers obtained in this problem? the p-value is not the same in the table i am using. thank you
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 130 kissing couples, both people in 82 of the couples tended to lean more to the right than to the left. (Use a = 0.05.) 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 130 who do so differs from the expected value by at least a s much as what was actually observed? (Round your answer four decimal places.) 0.1880 x 0.4027 (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 H:P*2/3 O Ho: p = 2/3 H₂: P <2/3 O Ho: p= 2/3 H₂: P ≤ 2/3 OH: P-2/3 H₂: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 = -0.87 ✓ -0.87 P-value = 0.3844 ✓ 0.3853 State the conclusion in the problem context. O Reject the null hypothesis. There is sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3. O Do not reject the null hypothesis. There is sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3. O Reject the null hypothesis. There is not sufficient evidence to conclude that the true proportion of right-leaning behavior differs from 2/3.
