In recent poling, it has been suggested that the approval rating of a certain politician (the proportion of people polled that approve of his performance in office) is 40%. 1) Suppose we conduct a new poll consisting of 30 people. Assuming the suggested approval rating is correct, and the independence of people polled, if X was the number of people in this new poll who approve of the politician, what kind of distribution would x have and what are its parameters? 2) Assuming the facts in the previous problem, how many people would we expect to see in the new poll who approve of the candidate? Suppose the approval rating in the new poll is 30%. How many people would approve of the candidate in this case? 3) Again, given the facts in problem 1, what is the probability of seeing a higher approval rating in the new poll (more than expected in problem 2)?
