North Carolina births. The file NCbirths contains data on a random sample of 1450 births 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 purpose of this analysis, we will consider four racial groups: white, black, Hispanic, and other (including Asians, Hawaiian, and Native American).Use the variable MomRace, which gives the races with descriptive categories. (The variable RaceMom uses only numbers to describe the races).

a. Produce graphical displays of the birth weights (in ounces) separated by mothers' racial group.

Comment on both similarities and differences that you observe in the distribution of birth weight among the races.

b. Report the sample sizes, sample means, and sample standard deviations of birth weights for each racial group.

c. Explain why it's not sufficient to examine the four-sample means, note that they all differ, and conclude that all races do have birth weight distribution that differ from each other.
