Here are summary statistics for randomly selected weights of newborn girls: n = 236, x= 30.3 hg, s= 6.1 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 29.8 hg

![Here are summary statistics for randomly selected weights of newborn girls n= 236, x= 30.3 hg, s = 6.1 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from
the confidence interval 29.8 hg <u<31.2 hg with only 18 sample values, x= 30.5 hg, and s = 1.6 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. Yes, because the confidence interval limits are not similar.
C. No, because each confidence interval contains the mean of the other confidence interval.
O D. No, because the confidence interval limits are similar.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6d7833b3-8b29-4ead-956d-1fb7407b0bb6%2F8449f416-609a-4a05-93c7-baba491de4ed%2Fq1dbimh_processed.jpeg&w=3840&q=75)
