- You are a researcher seeking to determine if an experimental drug can effectively treat hyperglycemia, a condition characterized by excess glucose in the blood, often associated with Type I diabetes. You select 24 hyperglycemia patients to study, and you give half of them a pill containing the drug you are testing and the other half a placebo (a pill that lacks the drug ingredient). After an evening of fasting, you measure the amount of glucose in their blood the next morning. Write the null and alternative hypotheses appropriate for your study. Which treatment is your control group, and why does your experimental design require a control group? Describe the structure of a carbohydrate, and what are the functions of carbohydrates in the body? What test that we have used before in lab could you use to measure the amount of glucose in their blood? Describe how you would use this test to measure the amounts of glucose in their blood serum samples.
