Question

Are there social class differences in the number of traffic violations? Here are the sample means and standard deviations for the number of tickets given for each group: lower class (mean = 3.2, sd = 1.4), middle class (mean = 10.2, sd = 2.3), and upper class (mean = 4.5, sd = 1.1). Assume you had 50 drivers in each group. If used ANOVA to conduct this analysis, what is the null hypothesis?
