The thaily are not really bad but it’s just that a little bit too big and then I can do that lol but I’m just going outside and I’m going on the road right thanks for
A) mean = np
0.6(200) = 120
SD^2= np(1-p)
SD = sqrt(200(0.6)(1-0.6))
SD = 6.928
B) the mean of binomial distribution in this case is the average number of samples you’ll have to take before you achieve a sample of 200 where 60% of smokers who started smoking before 18.
