Independent Sample t test: Self-Esteem Scores of Male&Female

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 male? Use a one-tailed with an alpha =.01

b. Use the data to make a 95% confidence interval estimate of the mean difference in self-esteem between male and female

c. Write a sentence demonstrating how the results from the hypothesis test and the confidence interval would appear in a research report

Please be a simple and clear as possible using all mathematical calculation when needed.

Solution Summary

Formula for the calculation and Interpretations of the results are also included. Interactive excel sheet is included. The user can edit the inputs and obtain the complete results for a new set of data.
