Here are summary statistics for randomly selected weights of newborn girls: n = 218, x = 31.4 hg, s= 7.8 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 29.5 hg << 33.1 hg with only 19 sample values, x = 31.3 hg, and s = 3.7 hg? What is the confidence interval for the population mean p? ng <u<ng (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. OB. No, because each confidence interval contains the mean of the other confidence interval. Ο Ο Ο C. Yes, because the confidence interval limits are not similar. OD. No, because the confidence interval limits are similar.
