Here are summary statistics for randomly selected weights of newborn girls: n = 205, x = 33.9 hg, s= 7.5 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 33.0 hg < u<35.8 hg with only 15 sample values, x = 34.4 hg, and s = 3.1 hg? What is the confidence interval for the population mean u? hg <µ

Question
Here are summary statistics for randomly selected weights of newborn girls: n = 205, x = 33.9 hg, s= 7.5 hg. Construct a confidence interval estimate of the mean. Use
a 90% confidence level. Are these results very different from the confidence interval 33.0 hg < u<35.8 hg with only 15 sample values, x = 34.4 hg, and s = 3.1 hg?
What is the confidence interval for the population mean u?
hg <µ<hg (Round to one decimal place as needed.)
Are the results between the two confidence intervals very different?
O A. No, because each confidence interval contains the mean of the other confidence interval.
O B. Yes, because the confidence interval limits are not similar.
OC. No, because the confidence interval limits are similar.
O D. Yes, because one confidence interval does not contain the mean of the other confidence interval.
