1) Is there a relationship between maternal height and baby length?
My code:
proc reg data= birthw.birthweight;
model mheight = length;
run;

- State your null and alternative hypothesis: Honestly I am uncertain of how to write the hypothesis because I did not think they would be able to relate the variables but I believe they are related due to the correlation on the graphs I get using my code.
Your hypothesis isn't what you think the answer is, it's what the question is, which is defined for you. You need to translate the words into a statistical test comparison.
"The null and alternative hypotheses for this analysis are
H0: There is not a linear relationship between exposure and mortality (R=0)
H1: There is a linear relationship between exposure and mortality (R≠0)"
This looks more like what you want in the way of hypothesis testing.
