21. In the Preview for this Chapter, we discussed a study
by McGee and Shevlin (2009) demonstrating that an
individual's sense of humor had a significant effect
on how the individual was perceived by others. In one
part of the study, female college students were given
brief descriptions of a potential romantic partner.
The fictitious male was described positively and, for
one group of participants, the description also said
that he had a great sense of humor. Another group of
female students read the same description except it
now said that he has no sense of humor. After reading
the description, each participant was asked to rate the
attractiveness of the man on a seven-point scale from
1 (very unattractive) to 7 (very attractive) with a score
of 4 indicating a neutral rating.
a. The females who read the "great sense of humor"
description gave the potential partner an average
attractiveness score of M = 4.53 with a standard
%3D
deviation ofs =
1.04. If the sample consisted of
n = 16 participants, is the average rating signifi-
cantly higher than neutralu = 4)? Use a one-
tailed test with a = .05.
