Here are summary statistics for randomly selected weights of newborn​ girls: n=229​, x=30.4 ​hg, s=6.1 hg. Construct a confidence interval estimate of the mean. Use a 95​% confidence level. Are these results very different from the confidence interval 30.0 hg<μ<31.6 hg with only 17 sample​ values, x=30.8 hg, and s=1.6 ​hg?   What is the confidence interval for the population mean μ​?   hg<μ

Question
Here are summary statistics for randomly selected weights of newborn​ girls: n=229​, x=30.4 ​hg, s=6.1 hg. Construct a confidence interval estimate of the mean. Use a 95​% confidence level. Are these results very different from the confidence interval 30.0 hg<μ<31.6 hg with only 17 sample​ values, x=30.8 hg, and s=1.6 ​hg?
 
What is the confidence interval for the population mean μ​?
 
hg<μ<hg ​(Round to one decimal place as​ needed.)
 
Are the results between the two confidence intervals very​ different?
 
A. ​Yes, because one confidence interval does not contain the mean of the other confidence interval.
 
B. ​No, because the confidence interval limits are similar.
 
C. ​Yes, because the confidence interval limits are not similar.
 
D. ​No, because each confidence interval contains the mean of the other confidence interval.
