Guéguen, Jacob, and Lamy (2010) wondered if listening to romantic songs would affect the dating behavior of the French heterosexual women who participated in their study. The women were randomly assigned to listen to either a romantic song (“Je l’aime à Mourir,” or “I Love Her to Death”) or a nonromantic song (“L’heure du Thé,” or “Tea Time”) while waiting for the study to begin. Later in the study, an attractive male researcher asked each participant for her phone number. Of the women who listened to the romantic song, 52.2% gave their phone number to the researcher, whereas only 27.9% of the women who listened to the nonromantic song gave their phone number to the researcher.

e. What is the best type of graph to depict these results? Explain your answer. 

f. Create the graph you described in part (e) using software without changing any of the defaults.
