Question 17 Influencing Voters A study is conducted to see if there is evidence that a recorded phone call is more effective than a mailed flyer in getting votes to support a certain candidate. The study assumes a significance level of α=0.05. (a) What is the conclusion in the context of this study if the p-value for the test is 0.017? Reject H0: There is evidence that a phone call is more effective than a flyer. Do not reject H0: There is no evidence of a difference between a phone call and a flyer. (b) In the conclusion in part (a), which type of error are we possibly making: Type I or Type II? Type I Type II (c) What is the conclusion in the context of this study if the p-value for the test is 0.15? Reject H0: There is evidence that a phone call is more effective than a flyer. Do not reject H0: There is no evidence of a difference between a phone call and a flyer. (d) In the conclusion in part (c), which type of error are we possibly making: Type I or Type II? Type I Type II
