d. If a sample of 400 is​ taken, how does this change your answers to​ (a) through​ (c)?If a sample of 400 is​ taken, what is the probability that in the sample fewer than 26​% are more likely to buy stock in a company based in Country​ A, or shop at its​ stores, if it is making an effort to publicly talk about how it is becoming more​sustainable?
