HOW DO YOU TEST FOR THESE ASSUMPTIONS

In which one of the following situations would it be most appropriate to use an ANOVA to analyze the data? A professor is interested in whether a research mentoring program can help students gain admission to graduate school. She randomly assigns 90 students who plan to apply to graduate school to one of three groups: (1) a one-semester research mentoring program, (2) a two-semester research mentoring program, or (3) no mentoring program. She then follows the students and records whether each student gained admission to a graduate program. A medical researcher wanted to measure the dosage effects of a new medication on the A1C levels of people with pre-diabetes symptoms. The A1C test is a blood test that returns a number (for example, 6%) that reflects how well a person’s blood sugar levels have been controlled over the last several months. The researcher randomly assigned the 60 participants into three conditions: (1) placebo group (no medication), (2) 100 mg of medication, or (3) 200 mg of medication. At the end of 30 days, the A1C levels of each participant was measured
