please solve all parts( A- E)  by using R studio 

the birthweights.csv dataset. This
contains information about various pregnancy outcomes related paternal and maternal attributes.
(a) Consider the variables LowBirth Weight and Birthweight (in pounds). What type of data are
these variables? Are they attempts to measure the same attribute?
(b) Write out a model that seeks to predict the birth weight of an infant as a function of some
predictor variables available in the dataset. Also provide 2 confounding factors that are not
available in the dataset that may limit the utility of such a model.
(c) Construct a histogram of birth weights for the mother smoking group, and a seperate his-
togram for the mother non-smoking group.
(d) Based on your answer to (c), compute an appropriate measure of center and dispersion for
each group and comment on an differences that exist.
(e) Which variable is more continuous, fage (father's age) or mnocig (mother's number of cigarettes).
Explain how you've determined that.
