does it give level of confidence?

hockeychick23 · Answer

no it doesn't give the level of confidence

perl · Answer

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

perl · Answer

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

perl · Answer

yes

perl · Answer

the other options are not symmetric about the mean
