2. Pullan et al. (1994) investigated the use of transdermal nicotine for treating ulcerative colitis. TH plasma nicotine level at baseline was 0.5 ± 1.1 ng/ml (mean ± SD; n = 35). After six weeks of treatı plasma level was 8.2 + 7.1 ng/ml (n = 30). (1) Is it more likely that the nicotine levels are sampled from a Gaussian or a lognormal distributic did you reach that conclusion? (2) Apply an appropriate analysis to get a 95% confidence interval of the nicotine level enhanceme %3!
