anh
Here are summary statistics for randomly selected weights of newborn girls: n3214, x 32.6 hg, s 7.8 hg. Construct a confidence interval estimate of the mean.
Use a 99% confidence level. Are these results very different from the confidence interval 29.9 hg<p< 35.9 hg with only 13 sample values, x- 32.9 hg, and s=3.6
hg?
What is the confidence interval for the population mean u?
||hg <p< 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. Yes, because one confidence interval does not contain the mean of the other confidence interval.
O C. No, because the confidence interval limits are similar.
D. No, because each confidence interval contains the mean of the other confidence interval.
