Numerous studies have found that males report higher

self-esteem than females, especially for adolescents

(Kling, Hyde, Showers, & Buswell, 1999). Typical

results show a mean self-esteem score of M 39.0 with

SS 60.2 for a sample of n 10 male adolescents and

a mean of M 35.4 with SS 69.4 for a sample of

n 10 female adolescents.

a. Do the results indicate that self-esteem is

significantly higher for males? Use a one-tailed

test with .01.

b. Use the data to make a 95% confidence interval

estimate of the mean difference in self-esteem

between male and female adolescents.

c. Write a sentence demonstrating how the results

from the hypothesis test and the confidence interval

would appear in a research report.
