If the sample mean is 96, which of the following is most likely the range of possible values that best describes an estimate for the population mean? A. (80,112) B. (78,110) C. (76,108) D. (82,114)

OpenStudy (perl):

does it give level of confidence?

OpenStudy (hockeychick23):

no it doesn't give the level of confidence

OpenStudy (perl):

all you need to use is the fact that the range is symmetric about the mean

OpenStudy (perl):

the range will look like ( mean - k , mean + k )

OpenStudy (hockeychick23):

ok so then its just +-16 like the first 1?

OpenStudy (perl):

yes

OpenStudy (perl):

the other options are not symmetric about the mean

OpenStudy (hockeychick23):

ok, thanks!
