In a study on the fertility of married women, two groups of childless wives aged 25 to 29 were selected at random, and each was asked if she eventually planned to have a child. One group was selected from among wives married less than two years and the other from among wives married five years. Suppose that 338 of the 400 wives married less than two years planned to have children some day compared to 353 of the 450 wives married five years. Can we conclude that the proportion of wives married less than two years who planned to have children is significantly higher than the proportion of wives married five years? Make use of a P-value. Click here to view page 1 of the normal probability table. Click here to view page 2 of the normal probability table. Let wives married less than two years correspond to population 1, let wives married five years correspond to population 2, and let a success be planning to have children some day. What are the null and alternative hypotheses? A. Ho: P₁ =P2 H₁: P1 P2 D. Ho: P1 P2 B. Ho: P1 P2 H₁ P1 P2 E. Ho: P1 P2 H₁: P1 P2 C. Ho: P₁ #P2 H₁ P1 P2 F. Ho P1 P2 H₁: P1 P2 H₁: P1 P2 Find the test statistic, z. (Round to two decimal places as needed.)
