In a study on the fertility of married women conducted by Martin O'Connell and Carolyn C. Rogers for the Census Bureau in 1979, 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 240 of the 300 wives married less than two years and planned to have children someday compared to 288 of the 400 wives married for five years. Can we conclude that the proportion of wives married less than two years who planned to have children are significantly higher than the proportion of wives married five years? State the null and alternative hypotheses. A)H ₀ P₁ = P₂ Ha:P₁<P₂ b)H ₀:P₁-P₂=0 Ha:P₁-P₂≠0 C)H₀:P₁=P₂ H₁a: P₁ > P₂ d)H₀:P₁=P₂ Ha: P₁≠P₂
