At a university, 12% of students smoke. Calculate the expected number of smokers in a random sample of 140 students from this university (please do not round your answer): The university gym opens at 9 am on Saturday mornings. One Saturday morning at 8:55 am there are 24 students outside the gym waiting for it to open. Should you use the same approach from part (a) to calculate the expected number of smokers among these 24 students? No, it is unlikely that smoking habits and waking up early to go to the gym on Saturday are independent Yes, it is reasonable to believe that people who go to the gym when it first opens on Saturday mornings is a representative sample
