you are asked to conduct a study to determine whether
there is an association between consumption of milk proteins and
levels of serum antibodies in children. You randomly select 50
children previously enrolled in a clinical trial and they are the
sample for the study. You select an alpha of 0.05 and a power of
0.80. Talk about the sample size of 50 participants. Why or why
isn't this a good size sample?

You have conducted a case-control study to determine the association between exposure to lead and development of cognitive disorders. Exposure data were collected from measuring blood samples and outcomes data from medical records. Participants were randomly selected to be included into the study. The investigator who obtained the exposures and outcomes data was blinded to the outcome status of the participant. In your study, you find an OR of 1.01. However, the actual association between exposure to lead and cognitive...

3. Suppose that you are asked to conduct a study to determine whether smaller class sizes lead to improved student performance of fourth graders. If you could conduct any experiment you want, what would you do? Be specific. More realistically, suppose you can collect observational data on several thousand fourth graders in a given state. You can obtain the size of their fourth-grade class and a standardized test score taken at the end of fourth grade. Why might you expect...

In Data 4.1 on page 258, we examine a study in which mice were randomly assigned to either a normal light/dark cycle or to have a light on around the clock. According to the paper describing that study, "The global increase in the prevalence of obesity and metabolic disorders coincides with the increase of exposure to light at night." The study is examining whether light at night plays a causal role in the obesity epidemic. In Data 4.1, we examine...

In a study of 380 diabetics and nondiabetics, patients were classified as underweight, normal weight, overweight and obese according to their diabetes status. The probability of being normal weight is 0.31 and the probability of having diabetes is 0.39. If you select two individuals from the population, the probability of being diabetic and normal weight is 0.09. What is the probability that either of the two randomly selected individuals (or both) will be diabetic or normal weight? a. Pr (diabetic...
