Is approximately normal. 0 Yes, the conditions are satisfied. This Is important because it allows us to say thatjil Is approximately binomial. O No, the conditions are not satised. This is important because it allows us to say that ii is approximately nOrmal. O No, the conditions are not satised. This is important because it allows us to say that ii is approximately binomial
