Concept explainers
Many people blame Wall Street greed for causing the economic crisis that gripped the nation in late 2008. In February 2009, the Harris Poll surveyed 1,010 Americans, using the statement that people on Wall Street are “as honest and moral as other people.” The number giving each response is summarized in the table below:
Agree 707
Disagree 263
Not sure 40
Based on these results, if you ask a randomly selected American this question,
(a) What is the probability that a randomly selected American thinks that people on Wall Street are less honest than other people?
(b) What is the probability that he or she cither agrees or disagrees?

Look at the two line graphs shown in the following fig- ures. One is a good representation of his data, and the other should get as much use as Bob's treadmill before his heart attack.

Compare the two graphs. Do they repre- sent the same data set, or do they show totally different data sets? b. Assume that both graphs are made from the same data. Which graph is more appropriate and why?arrow_forward
