hg. Construct a confidence interval estimate of the mean. Use a 9898%

confidence level. Are these results very different from the confidence interval 30.530.5

hgless than34.334.3

hg with only 2020

sample values, x overbarxequals=32.432.4

hg, and sequals=3.33.3

hg?

What is the confidence interval for the population mean mu?

nothing

hgless than

hg (Round to one decimal place as needed.)

Are the results between the two confidence intervals very different?

A.

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

B.

No, because the confidence interval limits are similar.

C.

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

D.

Yes, because the confidence interval limits are not similar.
