Chapter 17, Problem 22P

1. In the Preview for this chapter we presented a research study demonstrating that romantic back­ ground music increases the likelihood that a woman will give her phone number to a man she has just met

(Guéguen, Jacob & Lamy, 2010). The frequency distribution for the study is reproduced in the fo11owing table.

Use a chi-square test forindependence with

a = .05 to determine whether the data show a significant relationship between the type of music and the behavior of the female participants.

Compute the ph1-coefficient lo measure the strength of the relationship.
