![Here are summary statistics for randomly selected weights of newborn girls:n=157, x=28.8 hg, s=7.2 hg. Construct a confidence interval estimate of the mean.
Use a 99% confidence level. Are these results very different from the confidence interval 26.1 hg <u<30.5 hg with only 15 sample values, x= 28.3 hg, and s 2.8
hg?
What is the confidence interval for the population mean u?
|hg <p< hg (Round to one decimal place as needed.)
Are the results between the two confidence intervals very different?
O A. Yes, because one confidence interval does not contain the mean of the other confidence interval.
O B. No, because each confidence interval contains the mean of the other confidence interval.
O C. Yes, because the confidence interval limits are not similar.
O D. No, because the confidence interval limits are similar.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fec8c19c0-6bc9-43b6-b414-acd6330be112%2Fb5877967-5789-457b-8601-bd821d54d9b7%2Fxo69l5_processed.jpeg&w=3840&q=75)
