A grocery store manager wants to know if displaying cranberries near the entrance to the store increases the proportion of shoppers who buy them. To determine this, the manager flips a coin each morning to decide whether to place the cranberries near the entrance that day or to locate them in the produce section. The manager takes a random sample of shoppers over several days and calculates 1°p= the proportion of shoppers who buy cranberries when they are near the store entrance, and 2"p= the proportion of shoppers who buy cranberries when they are in the produce section. Which of the following is a correct set of hypotheses for the appropriate test of significance? o H, :p=0; H, : p + 0 O Ho:p=0; H, : p >0 a O H.: P- P2 = 0; H.: P - P2 ± 0 O H,: P - P2 = 0; H,: P, - P2 <0 o H, : P - P2 = 0; H¸:P, - P2 >0
