tutor3 : Hello Student, May I help you with your Math problems?
student : In the 1990s, the U.S. Justice Department and other groups studied possible abuse by Philadelphia police officers in their treatment of minorities. One study, conducted by the ACLU analyzed whether African American drivers were more likely than others in the population to be targeted by police for traffic stops. Researchers studied the results of 262 police car stops during one week in 1997. Of those, 207 of the drivers were African American, or 79% of the total. At that time, Philadelphia’s population was 42.2% African American. Does the number of African Americans stopped give strong evidence of possible bias, being higher than you’d expect if we take into account ordinary random variation? Explain your reasoning in a report of at most 250 words.
