2. 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 ñ = the proportion of
shoppers who buy cranberries when they are near the store entrance, and P2 = the proportion of shoppers
who buy Cranberries when they are in the produce section. Which of the following is a correct set of
hypothesis for the appropriate test of significance?
(a) H - P = 0; HP - P. +0
(b) H. P.-=0; H P - p, > 0
(c) H p. - p =0; HP.-P. +0
(d) H P.-P. =0; H P.-P, <0
(e) HP - P2 = 0; HP-p, > 0
