Research results indicate that physically attractive people are also perceived as being more intelligent (Eagly, Ashmore, Makhjani, & Longo, 1991). As a demonstration of this phenomenon, a researcher obtained a set of 10 photographs, 5 showing men who were judged to be attractive and 5 showing men who were judged to be unattractive. The photographs were shown to a sample of n = 25 college students and the students were asked to rate the intelligence of the person in the photo on a scale from 1 to 10. For each student, the researcher determined the average rating for the 5 attractive photos and the average for the 5 unattractive photos. The collected data are presented below.

Attractive Averages:	6	8	6	7	7	6	7	8	7	7	8	7	9	8	7	8	8	6	6	10	7	8	8	7	8
Unattractive Averages:	4	4	3	6	4	5	4	5	6	6	5	4	5	5	5	4	5	6	5	2	6	4	5	4	4

Test whether attractive individuals were rated more intelligent than unattractive individuals. Use = .05.

Identify the:

• Dependent variable(s):
• State Hypotheses mathematically:

and in words. The hypotheses are the same for both DVs.

Proper t-test:

One-tailed or two-tailed?

After running the t-test, create graphs to show the means and standard errors of both conditions. Please include a title that makes the graph easy to understand.

What are the results of the F-test for homogeneity of variance? (are variances equal for both?)
