Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

Question

Are the results between the two confidence intervals very different?

Here are summary statistics for randomly selected weights of newborn girls: n=244, x 28.3 hg, s=7.1 hg. Construct a
confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence
interval 26.5 hg<p<30.7 hg with only 14 sample values, x 28.6 hg, and s = 2.9 hg?
What is the confidence interval for the population mean p?
27.2 hg<p< 29.4 hg (Round to one decimal place as needed.)
Are the results between the two confidence intervals very different?
O A. No, because each confidence interval contains the mean of the other confidence interval.
OB. No, because the confidence interval limits are similar.
O C. Yes, because the confidence interval limits are not similar.
D. Yes, because one confidence interval does not contain the mean of the other confidence interval.
