more likely to offer windrowing (mowing and piling) of hay services, producers in State A or producers in State B. Of the A study was conducted to determine who 560 producers from State A, 179 were willing to offer windrowing services. Of the 938 producers from State B, 386 were willing to offer windrowing services. The researchers want to know if the proportion of producers who were willing to offer windrowing services differs for the two areas, State A and State B. Complete parts a through f below. O A. P1 +P2 O B. (P, + P2)? OC. (P1 - P2)? D. P1 -P2 b. Set up the null and alternative hypotheses for testing whether the proportion of producers who were willing to offer windrowing services differs in State A and State B. A.
