Which of the following best corresponds to a biomedical perspective on disease? -
ANSWERSDisease is due primarily to the influence of pathogens (e.g. viruses, bacteria,
parasites)
Which of the following is a correct interpretation of a p-value of 0.03? - ANSWERSthere is

Researchers are interested in studying the relationship between excessive caffeine intake and
gastroesophageal reflux disease (GERD). They recruit a sample of individuals; about half of them

caffeine. What type of study is this? - ANSWERScase-control
