So they decide to ask a simple random sample of 160 students if they have experienced extreme levels of stress during the past month. Subsequently, they find that 10% of the sample replied yes to the question. Assuming the true proportion is 15%, which they tell us up here, they say 15% of the population of the 1,750 students actually have experienced extreme levels of stress during the past month. So that is the true proportion. So let me just write that. The true proportion for our population is 0.15. What is the approximate probability that more than 10% of the sample would report that they experienced extreme levels of stress during the past month?
