This question builds off the previous one. The researcher measures the anxiety of 50 persons then plays Mozart’s “Eine Kleine Nachtmusik” for them. Following that the researcher measures their anxiety again. (Note that anxiety is measured on a scale from 1 to 7, with higher numbers indicating increased anxiety.) Does the study support her hypothesis? Compute the upper bound of the confidence interval using the following data: mean of the difference scores (subtract pretest from posttest): {m} standard error of the difference scores: {v} Use the following website for this question: https://www.statskingdom.com/paired-t-test-calculator.html Ignore the first set of input options. Scroll down a bit and look for these three options: “enter raw data”, “enter raw data from “excel”, and “enter summarized data.” You want that last option (i.e., summarized data). After you click on that you’ll see fields that correspond to the data in this question. You should probably enter a better label in the “Name” field, such as pretest/posttest. The output is a bit wonky, but look for “3. Test Statistic.” The last sentence in that section begins with, “The 95% confidence interval…” That’s the CI for the data provided in this question. Report the upper bound.
