Astudy is conducted to investigate whether a recorded phone call is more effective than a flyer in persuading voters to vote for a particular candidate. the response variable is the proportion of voters planning to vote for the candidate, with p1 and p2⁢ representing the proportions for the two methods (receiving a phone call and receiving a flyer, respectively.) the sample statistic of interest is p^1-p^2. we are testing h0: p1=p2vs ha: p1> p2. a randomization distribution of differences in proportions, p^1-p^2, for this test is shown in the figure below.

(a) four possible sample statistics are given, along with four possible p-values. match the statistics with the p-values.
