Criminal justice researchers want to conduct a study on racial profiling in Pennsylvania by police officers on the Turnpike after a newspaper article reports that White officers were more likely to stop non-White drivers. They collect a random sample of 250 recorded traffic stops and collect the race of the police officer and the race of the driver. Use the following data to conduct a Chi-Square test for differences between the groups - make sure you state the null hypothesis and our conclusion at the 0.05 significance level.

Race of Officer

Race of Driver White Non-White

White 96 58

Non-White 64 32

a) State the null hypothesis

b) Conduct a Chi-Square test to test for differences between the groups.

c) Using the 0.05 significance level, do you accept or reject the null hypothesis? What can you conclude?
