# Question: According to the U S Census Bureau 20 of the workers

According to the U.S. Census Bureau, 20% of the workers in Atlanta use public transportation. If 25 Atlanta workers are randomly selected, what is the expected number to use public transportation? Graph the binomial distribution for this sample. What are the mean and the standard deviation for this distribution? What is the probability that more than 12 of the selected workers use public transportation? Explain conceptually and from the graph why you would get this probability. Suppose you randomly sample 25 Atlanta workers and actually get 14 who use public transportation. Is this outcome likely? How might you explain this result?
