Question 2 2 pts Consider the following conclusions from a study: (Assume all are statistically significant.) 1. Those who were 10-29 pounds overweight were 1.25 times more likely to require knee replacement surgery by age 65 than those who were normal weight. 2. Those who were 30-49 pounds overweight were 1.31 times more likely to require knee replacement surgery by age 65 than those who were normal weight. 3. Those who were 50-69 pounds overweight were 1.45 times more likely to require knee replacement surgery by age 65 than those who were normal weight. Which of Hill’s criteria is best supported by our findings? O Dose-Response Strength of Association Temporal Precedence Biological Plausibility 00 Consistency of Association Question 5 2 pts In a study examining the association between caffeine intake and sleep disturbances, a relative risk of 1.35 (95%CI: 0.95-1.75) was found. This shows assortment that caffeine can prevent sleep disturbances that caffeince is a risk factor for sleep distrbances no association Question 8 2 pts Conclusions about the population based on sampled data are most likely to be reliable and valid if each person in the population has an understanding of the study and its implications o the same overall demographics and characteristics an equal opportunity to ask questions an equal probability of being selected for the study Question 11 2 pts The odds ratio for the association between wearing tight shoes and developing plantar warts on the feet was 5.55. (p=,5). Which of the following of Hill’s criteria has been shown? None of these. Temporal Precedence Biological plausibility Strength of association Question 12 2 pts A process by which participants have an equal probability of being assigned to any of the study groups is called This process minimizes any confounding effects by balancing out the potential confounding factors among the groups random selection random assignment random drawing random error Question 15 2 pts As the sample size increases, the probability that the results are due chance remains stable flucuates based on sample size increases decreases
