Question

We are interested in determining whether a sample of students at FAU differ significantly from the national college population in terms of the average amount of time spent in college. To evaluate this, we need to conduct a(n)

independent samples t-test

dependent samples t-test

one-sample t-test

any of these would be appropriate

Answer 1

Here you are going to test the difference between sample of student at FAU and National college population in terms of the average amount of time spent in college.

Here you are conducting one sample t-test. Because here Sample mean is comparing with population mean of time spent in college. In this case, student at FAU is sample and Population is national college student.

One sample t test used whether the sample mean is statistically different from a hypothesized population mean.

Independent samples t- test cannot be used because for this test you need two independent samples.

There is no possibility of using dependent test because treatments are not applying on same subject.
