Show transcribed image text Attempts: Keep the Highest: /4 4. Choosing the appropriate test statistioc For the following two research scenarios, identify the most appropriate hypothesis test and its statistic. Research Scenario 1: The eating disorder anorexia nervosa is characterized by extremely low body weight and body image distortion. Individuals with anorexia control their body weight by starving themselves and/or exercising excessively. Because anorexia commonly manifests in adolescence, when bone density and bone metabolism are changing dramatically, women who had or have anorexia are vulnerable to bone fractures throughout their lives. You design a study to examine whether a group of women with anorexia have higher intelligence than the general population, which has an average IQ of 100 with a standard deviation of 15. Which hypothesis test is most appropriate for this research design (assuming the test assumptions are satisfied)? O A two-sample t test A paired t test A single-sample z test The appropriate test statistic is Research Scenario 2: Randy Frost i s an expert on compulsive hoarding, which appears to be a common variation of e to search
