Consider an urban ecologist who is interested in whether the presence of high-voltage power lines influences the number of eggs laid by birds nearby. She plans to conduct a two-sample t-test and will assume that the population variances are equal. Her data is as follows:

Near (group 1): mean = 6.1, SD = 0.35, n = 12

Far (group 2): mean = 5.8, SD = 0.30, n = 9

What is the 95% confidence interval for the difference between the two means?
