Suppose a sample of 20 Amserican is selected as part of the study of the state of the nation. Compute the probability that exactly 4 of the 20 Americans surveyed are satisfied with the way things are going in the United States Compute the probability that at leeast 2 of the Americans surveyed are satisfied with the way things are going in US. Fro the sample of 20 Americans compute the expected number of Americans who are satisfied with the way things are going in US. For the sample of 20 Americans, compute the variance and standard deviation of the number of Americans who are satisfied with the way things are going in the US.
