Chapter 4, Section 2, Exercise 067 Influencing Voters: Is There a Difference in Effectiveness between a Phone Call and a Flyer? A study is conducted to investigate which method, a recorded phone call or a flyer, is more effective in persuading voters to vote for a particular candidate. Since in this case, the alternative hypothesis is not specified in a particular direction, the hypotheses are Ho : P. = Py vs H. : P. # Py . A randomization distribution for , - py using n = 1000 for this test is shown below. 120 - 100 - 80 Frequency 60 40 20 . 0 - -0.6 -0.4 -0.2 0.0 0.2 0.4 0.6 Difference(a) Pe - pf = 0.19 is a possible sample statistic, Five possible p-values are given below. Select the most accurate p-value for the sample statistic P - p, . O p-value = 0.14 O p-value = 0.351 O p-value = 0.832 O p-value = 0.006 O p-value = 0.085 (b) Pc - py = -0.43 is a possible sample statistic. Five possible p-values are given below. Select the most accurate p-value for the sample statistic Pc - Pf . O p-value = 0.351 O p-value = 0.832 O p-value = 0.006 O p-value = 0.085 O p-value = 0.14
