Question: 3 Here are summary statistics for randomly selected weights of newborngirls: n=206, x=32.1 hg, s=6.2 hg. Construct a confidence interval estimate of the mean. Use

Here are summary statistics for randomly selected weights of newborngirls: n=206, x=32.1 hg, s=6.2 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 31.1 hg<<33.7 hg with only 19 samplevalues, x=32.4 hg, and s=1.9 hg?

What is the confidence interval for the population mean ?

hg<< hg

(Round to one decimal place asneeded.)

Are the results between the two confidence intervals verydifferent?
