The file NCbirths contains data on a random sample of 1450 birth records in the state of North Carolina in the year 2001. This sample was selected by John Holcomb, based on data from the North Carolina State Center for Health and Environmental Statistics. One question of interest is whether the distribution of birth weights differs among mothers' racial groups. For the purposes of this analysis, we will consider four racial groups as reported in the variable MomRace: white, black, Hispanic, and other (including Asian, Hawaiian, and Native American). Use Levene's test to determine if the condition of equality of variances is satisfied. Report your results. data is in stat2datat.
