Answer ASAP please In full
Here are summary statistics for randomly selected weights of newborn girls: n= 153, x=27.5 hg, s=7.2 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from
the confidence interval 25.5 hg <u< 28.9 hg with only 19 sample values, x= 272 hg, and s=2.9 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. Yes, because one confidence interval does not contain the mean of the other confidence interval.
O B. No, because each confidence interval contains the mean of the other confidence interval.
O C. No, because the confidence interval limits are similar.
O D. Yes, because the confidence interval limits are not similar.
