Question

I need help with this exercise, please answert part B as well. Thanks in advance.

Here are summary statistics for randomly selected weights of newborn girls: n= 161, x= 26.7 hg, s= 6.5 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence
level. Are these results very different from the confidence interval 25.8 hg < u< 28.6 hg with only 17 sample values, x= 27.2 hg, and s = 2.3 hg?
What is the confidence interval for the population mean p?
hg <u< hg (Round to one decimal place as needed.)

Are the results between the two confidence intervals very different?
O A. Yes, because the confidence interval limits are not similar.
O B. No, because the confidence interval limits are similar.
OC. No, because each confidence interval contains the mean of the other confidence interval.
D. Yes, because one confidence interval does not contain the mean of the other confidence interval.
