You're doing an experiment to test whether students fed a new element, "brainium", will do better on tests. 50 students are fed 250 mg of brainium everyday for a week, and 50 students are fed 250 mg of a placebo (something that looks like brainium, but isn't) everyday for a week. After the week of treatment all students are given the same test. What is the dependent variable? Select the best answer. The students. The amount (250 mg). Time. The test scores. The type of pill (brainium or placebo) The 50 students fed the brainium. The 50 students fed the placebo.

I really need help in examining the data in the table and graph in addition to divinding the groups (attached in images). It shows the blood glucose levels of six individuals tested in a laboratory. After baseline (i.e., time 0 minutes) blood glucose levels were measured and recorded, each person drank a liter of milk. Blood glucose levels were again measured at 15, 30, 45, and 60 minutes after drinking the milk.
Dr. Vanier’s daughter Lexy thinks that the snacking habit alone does not cause weight loss. She believes that one needs to combine no snacking with the elimination of carbohydrates in their meals. Please explain how Dr. Vanier may test this hypothesis by describing the research design. Specify the independent variable(s), dependent variable(s), and the name of the design. Finally, describe what she needs to find (i.e., what type of effect and what it looks like) in the experiment to support her hypothesis. ( name the IV(s); 1name the DV(s); name the design; then explain the effect that will support the hypothesis)
When comparing two multivitamins in the store, you see that one has 500% of the daily value for a particular vitamin, while the other has 100% of the daily value for that vitamin. Is the one with 500% of the daily value necessarily better for your health? Explain your answer.

The confidence interval is reported as follows: Lower 95% CI < p < Upper 95% CI For this question you will be calculating the confidence interval but only reporting the Upper 95% CI using the Agresti-Coull Method. ( (you'll need to know the whole 95% CI for a future question) Do NOT use calculations from previous questions, this is a new scenario. In the Invisible Gorilla Experiment, 24 students were watching the video, only 7 noticed the gorilla. Calculate the 95% CI using the Agresti-Coull method, but only report the Upper 95% CI. Report your answer to 3 decimals.

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. Identify the dependent variable…
Which question will your experiment investigate? (select one and delete the others) How does temperature affect how lactase drops work to break down lactose into glucose and galactose? What variable will you change in this experiment? This is also called the Independent variable. How will you change it? What variable will you measure in this experiment to determine the effect of the variable you changed? This is also called the Dependent variable. How will you measure it? The temperature is the variable that would be changed and it would be changed by placing the milk in a hot bath and another one in an ice bath What variables will you keep the same in this experiment? milk (lactase) Check off the items in this list that you would use for this experiment. You may add any items you feel you would need. O skim milk (which contains lactose) O Lactase drops O Graduated cylinder O Eye dropper O Ice cubes O pH paper O Hot plate O Mixing spoon O Thermometer O Vinegar (acidic) O Test tubes O…
