Question #1: find (i) the relative risk of ever having asthma for girls compared to boys, and (ii) percent increase in risk for girls compared to boys. (Hint: consider the group of boys as the baseline). a. (i) relative risk = 1.301, (ii) percent increase = 11.66% b. (i) relative risk = 0.734, (ii) percent increase = -11.66% c. (i) relative risk = d. (i) relative risk = 0.713, (ii) percent increase = -28.66% 0.813, (ii) percent increase = 18.66% QUESTION 2 Question #2: find (i) the odds of ever having asthma for boys, (ii) the odds of ever having asthma for girls, and (iii) the odds ratio of comparing the odds of ever having asthma for girls compared to boys. a. (i) Odds for boys: 0.164, (ii) Odds for girls: 0.114, (iii) Odds ratio: 1.438. b. (i) Odds for boys: 0.114, (ii) Odds for girls: 0.164, (iii) Odds ratio: 1.395. c. (i) Odds for boys: 0.186, (ii) Odds for girls: 0.126, (iii) Odds ratio: 0.677. d. (i) Odds for boys: 0.171, (ii) Odds for girls: 0.133, (iii) Odds ratio: 0.778.
