Question
Here are summary statistics for randomly selected weights of newborn girls: n = 211, x= 33.7 hg, s= 6.8 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence
interval 32.1 hg <µ< 34.3 hg with only 16 sample values, x= 33.2 hg, and s = 2.6 hg?
What is the confidence interval for the population mean u?
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 each confidence interval contains the mean of the other confidence interval.
O C. 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.
