Read the following eight scenarios and determine what type of t-test you would use to analyze the data. You should not calculate anything - just decide which test is most appropriate for the scenario: (8 points) 1. A researcher was interested in knowing whether a visible facial piercing would negatively impact perceived competence of job applicants when applying and interviewing for a job. To study this, a researcher asked an HR manager to complete the Acme Employability Scale which as a mean u = 10 for several applicants. A sample of n = 9 job applicants with visible facial piercings were interviewed and their scores on the Employability Scale were recorded. Which type of t-test should you use to analyze these data? a. One-sample t-test b. Independent measure (sample) t-test c. Repeated measure (sample) t-test 2. A researcher believes that a new biofeedback technique that uses virtual reality will significantly reduce patient pain. She a recruits a sample of n = 9 patients for her study and asks them to rate their pain before and after the new biofeedback technique. Assume that the biofeedback scores are normally distributed which t-test would you use to test whether virtual reality approach significantly impacted patient pain. a. One-sample t-test b. Independent measure (sample) t-test c. Repeated measure (sample) t-test 3. A psychologist was interested in the impact that the Flint Water Crisis may have had on intelligence scores of school-aged children (6- 10 years old) and administered an standardized intelligence test with a u =100 to a random sample of n = 2500 of school age children from the affected areas and obtained a sample mean IQ of M = 95. Which type of t-test should you use to analyze these data? a. One-sample t-test
