1. State whether it will experimental or observational 2. If observational, identify which type specifically (retrospective cohort, prospective cohort, case-control, cross-sectional, ecological) 3. Briefly explain how you can tell what type of study it is. In 2010, we examined the medical records of 2,000 patients ages 53+ associated with Kaiser Permanente (large health care organization) who did NOT have kidney disease in 2005. Then, we look back in the records to see who took BZDs from 2000-2005. After that, we look to see who developed kidney disease from 2006 until 2008. We compared the rates of kidney disease among those who took the BZDs and those who didn’t.

The Wisconsin Fish and Game Department stocked a lake with 30% catfish, 15 % bass, 40% bluegill, and 15% Northern Pike. Five years later they took a random sample of 500 fish from the lake and found 120 catfish, 85 bass, 220 bluegill, and 75 Northern Pike. At the 5% level of significance, can we show that the distribution of fish changed over the 5-year interval? State and test appropriate hypotheses. State conclusions.
As a hospital administrator of a large hospital, you are concerned with the absenteeism among nurses' aides.

Vitamin E and the Risk of Prostate Cancer: Klien et al (2011) conducted the following study to determine the effect of vitamin E and selenium treatment on the risk of developing prostate cancer in healthy men. A total of 34,887 men from different study sites in the United States, Canada, and Puerto Rico were randomly selected. To be eligible to participate, the men had to take a rectal examination that showed he was not suspicious of having prostate cancer and be aged 50 years or older for black men and 55 years or older for all others. Each man was randomly assigned to receive one of four treatments: selenium, vitamin E, selenium and vitamin E together, or a placebo. The men were followed up after 8 years to see if they had developed prostate cancer or not. The main question of interest is to determine if the risk of developing prostate cancer differs by the treatment taken. The data are summarized in the table below: No Prostate Cancer Prostate Cancer Total Selenium 8,752 8,737 8,702…
