Question
Here are summary statistics for randomly selected weights of newborn girls:
interval estimate of the mean . Use a
n=232,
x=28.9
hg,
s=6.3
hg. Construct a confidence 98%
confidence level. Are these results very different from the confidence interval
27.3
hg<μ<30.3
hg with only
12
sample values,
x=28.8
hg, and
s=1.9
hg?What is the confidence interval for the population mean
μ?
nothing
hg<μ<nothing
hg (Round to one decimal place as needed.)Are the results between the two confidence intervals very different?
No, because the confidence interval limits are similar.
Yes, because one confidence interval does not contain the mean of the other confidence interval.
Yes, because the confidence interval limits are not similar.
No, because each confidence interval contains the mean of the other confidence interval.
