In a MS Word or similar document, with each question numbered, respond to each of the questions below. Be sure to show all of your math. Use standard mathematical operators: divide (/), multiply (x), add (+), and subtract (-), and include parentheses to show the order of operations where necessary.
To examine the association between indoor mold exposure and asthma among children, a random sample of households in Detroit, Michigan is recruited to par-ticipate in a study in 2011. Parents are interviewed about the child’s current lower respiratory symptoms, and air samples are taken inside the home on the same day as the interview to measure mold concentration. Calculate the absolute measure of effect for this study and interpret it using a complete sentence.
To examine whether insurance coverage is associated with discharge to a specialized post-acute care facility (e.g., rehabilitation, skilled nursing, etc.) after a trauma hospitalization, 2960 trauma patients from the National Trauma Databank in 2006 were assessed. The likelihood of discharge to a specialized facility was compared between trauma patients with Medicaid versus other insurance coverage. Calculate the ratio measure of effect for this study and interpret it using a complete sentence.
A study examines the association between family history of cancer and risk of laryngeal cancer. Laryngeal cancers were identified from a registry between 1992 and 2009 and histologically confirmed. Cancer patients were contacted and asked about laryngeal cancer history in any first-degree relative along with other risk factors.
Calculate and interpret the appropriate measure of effect.
A study that found that adult residents of a small town in New York who ate fish from a local PCB-contaminated river had a 1.5 times higher incidence rate of liver cancer compared to residents in the same town who did not consume fish from the same source during childhood. Calculate and interpret the appropriate absolute measure of effect.
