Research Question:A clinical psychologist is treating 25 patients with clinical depression. She wants to find out whether these patients score differently than the general population on an emotional response scale with a population mean μ = 9.5. She is only interested in whether there is a difference, but not in the direction of the difference at this point. Open the "Data Set 7" attachment under the "Excel Homework 7" header located in the Assignment Instructions folder and perform a single-sample t-test to evaluate this hypothesis.
