A random sample of the birth weights of 186 babies has a mean of 3103 g. These
babies were born to mothers who did not use cocaine during their pregnancies.
What is the best point estimate of the mean weight of babies born to mothers who
did not use cocaine during their pregnancies?
2000 g
16.69 g
3103 g
186 g
