Here are summary statistics for randomly selected weights of newborngirls: n=225,x=33.2hg, s=6.7

hg. Construct a confidence interval estimate of the mean. Use a90% confidence level. Are these results very different from the confidence interval32.3 hg<<34.5 hg with only14 samplevalues,x=33.4hg, and

s=2.4hg?

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?

A.

No, because the confidence interval limits are similar.

B.

Yes, because one confidence interval does not contain the mean of the other confidence interval.

C.

Yes, because the confidence interval limits are not similar.

D.

No, because each confidence interval contains the mean of the other confidence interval.
