Here are summary statistics for randomly selected weights of newborn girls: n= 185, x 33.5 hg, s=6.7 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level Are these results very different from the confidence interval 31.7 hg <u<34.5 hg with only 19 sample values, x= 33.1 hg, and s=2.4 hg? What is the confidence interval for the population mean p? hg <u< hg (Round to one decimal place as needed.) Are the results between the two confidence intervals very different? O A. No, because the confidence interval limits are similar. O B. Yes, because one confidence interval does not contain the mean of the other confidence interval. O C. Yes, because the confidence interval limits are not similar. O D. No, because each confidence interval contains the mean of the other confidence interval.
