Here are summary statistics for randomly selected weights of newborn girls: n=234, x=30.4 hg, s=7.9 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 27.8 hg<μ<33.4 hg with only 12 sample values, x=30.6 hg, and s=3.6 hg?

What is the confidence interval for the population mean μ?

__ hg <μ<__ hg (Round to one decimal place as needed.)

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
