Here are summary statistics for randomly selected weights of newborn girls: n= 152, x= 29.2 hg, s=6,6 hg, Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results
very different from the confidence interval 28.3 hg <u< 30.9 hg with only 13 sample values, x = 29.6 hg, and s= 2.1 hg?
What is the confidence interval for the population mean p?
28.1 hg<u< 30.3 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 each confidence interval contains the mean of the other confidence interval.
OC. Yes, because one confidence interval does not contain the mean of the other confidence interval
O D. No, because the confidence interval limits are similar.
