here are the summary stats for randomly selected weights of newborn girls n=245, x=32 hg s=6.4hg. construct a confidence interval estimate of the mean. use a 98% confidence level. are these reault very different from the confidence interval 31.0 hg<u<34.2 hg with only 13 sample values x=32.6 hg and s=2.2hg?
what is the confidence interval for the population mean?
hg<u<hg. round to one decimal place as needed
are the results between the two confidence intervals very different?
