Numerous studies have found that males repeat higher self esteem than females, especially for adolescents (Kling, Hyde, Showers, & Bussell, 1999). Typical results show a mean of self esteem score of M = 39.0 with SS = 60.2 for a sample of n= 10 male adolescent s and a mean of M =35.4 with SS =69.4 for a sample of n = 10 female adolescents.
a. Do the result indicate that self-esteem in significantly higher for males? Use a one tailed test with a =.01
b. Use the data to make a 95% confidence interval estimate of the mea 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.
