Researchers at an Alzheimer's institute are interested in the relationship between sleep apnea and early onset of senile dementia. In order to test this presumed relationship, researchers enrolled a group of participants from their patient database and observed both their performance on the Mini-Mental State Examination (MMSE) to diagnose the outcome, and an in- house sleep study to determine their apnea hypopnea index (AHI) score. Patients meeting a specific threshold for both score categories were then put into the following 2x2 table. Early onset of senile dementia No early onset of senile dementia Total Sleep Apnea Positive 67 301 368 Sleep Apnea Negative 40 303 343 Total 107 604 711 Round the following numbers to the 3rd decimal place. a. The prevalence (risk) ratio (same equation as relative risk) of dementia for sleep apnea vs, no sleep apnea is | b. The odds ratio of dementia for sleep apnea vs. no sleep apnea is c. The natural logarithm of the odds ratio is d. The standard error of the natural log of odds ratio is e. The 95% confidence interval of the odds ratio is Enter integers for question f. f. The expected values for Early onset of senile dementia are Early onset of senile dementia Sleep Apnea Positive Sleep Apnea Negative
