Here are summary statistics for randomly selected weights of newborn girls:

n=222

x =27.5

hg=6.6hg. Construct a confidence interval estimate of the mean. Use a

95% confidence level. Are these results very different from the confidence interval 26.8

hgless than<muμless than<29.0 hg with only 20 sample values, x overbarxequals=27.9 hg, and sequals=2.4 hg?
