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.)

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.
