The researcher obtains a random sample of 160 traffic violations recorded by the police and he organizes the sample data by the race of the driver. From census data for the city the researcher also determines the percentage of the city's entire population by race. Using the researcher's data, test whether the percentage of traffic violations recorded by race is significantly different from the racial breakdown of the city as a whole. Set alpha to .05 and round to two decimal places.
