Question

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

nequals

235

x overbar

equals32.8

hg,

sequals

7.9

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

confidence level. Are these results very different from the confidence interval

29.7

hgless than

muless than35.3

hg with only

sample values,

x overbar

equals32.5

hg, and

sequals

3.6

hg?

What is the confidence interval for the population mean

nothing

hgless than

muless thannothing

hg (Round to one decimal place as needed.)

Are the results between the two confidence intervals very different?

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

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

No, because the confidence interval limits are similar.

Yes, because the confidence interval limits are not similar.
