Stats Please anwser for: Does cocaine use appear to affect the birth weight of a baby? If there is an effect, explain how the weights are affected. Previous question to both these questions just in case: 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?

Please anwser for: Does cocaine use appear to affect the birth weight of a baby? If there is an effect, explain how the weights are affected.

Previous question to both these questions just in case:

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?

Compare the confidence interval from the previous question to this confidence
interval obtained from birth weights of babies born to mothers who used cocaine
during pregnancy:
2608g < µ < 2792g
Does cocaine use appear to affect the birth weight of a baby? If there is an effect,
explain how the weights are affected.

If there is an effect, explain how the weights are affected.
In the context of the previous problem, construct a 95% confidence interval estimate
of the mean birth weight for all such babies. Assume that the population has a
standard deviation of 696 g.
