Using Binomial Distribution, answer the following question (Part A & B) : According to a recent poll, 35% of US citizens approved of the job the President was doing at the time. Assume that this proportion was actually true for the whole of the US population. Part (a) majority a simple random sample of 15 citizens was selected. What is the probability that a (more than 5) approved of the job that the President was doing? Part (b) Suppose a simple random sample of 50 citizens was selected. What is the probability that a majority (more than 26) approved of the job that the President was doing?
