  1. Explain how loss to follow-up could bias findings in a cohort study of physical activity in college and subsequent diagnosis of diabetes.
  2. Explain how recall bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood (while age 18 to 24 years)
  3. Explain how selection bias could affect a case-control study of type 2 diabetes diagnosed in adults age 45 to 64 years and physical activity during young adulthood. Assume cases are identified as adult diabetic patients attending a diabetes management seminar at a local hospital and controls are selected from non-diabetic patients admitted to the hospital during the week the seminar was offered. Further assume that cases and controls are matched on age and sex.

In a study on the physical activity of people, researchers measured overall physical activity as the total number of registered movements (counts) over a period of time and then computed the number of counts per minute (cpm) for each subject. The study revealed that the overall physical activity of obese people has a mean of μ=322cpm and a standard deviation σ=92cpm. In a random sample of 100 obese people, consider x ̅, the sample mean counts per minute. Now suppose...

Physical activity of obese young adults. In a study on the physical activity of young adults, pediatric researchers measured overall physical activity as the total number of registered movements (counts) over a period of time and then computed the number of counts per minute (cpm) for each subject (International Journal of Obesity, Jan. 2007). The study revealed that the overall physical activity of obese young adults has a mean of μ = 320 cpm μ = 320   cpm and a...
