(a) Explanation Calculation: From the information given, the margin of error is 0.04, and from problem 17, the proportion of couples sharing two personality traits, and the proportion of having no traits in common are p ^ 1 = 289 375 , p ^ 2 = 23 571 . It is know that n = n 1 = n 2 . The confidence level is 99%. Critical value: Use the Appendix II: Tables, Table 5 (b): Confidence interval, Critical Values z c . In the level of confidence c column, locate the value of 0.99, or 99%. The corresponding Critical value z c is 2.58. Substitute 289 375 for p ^ 1 , 23 571 for p ^ 2 , 2.58 as z c , and 0.04 for E in the sample size formula (b) To determine Find the sample size.
