The brain volumes (
cm^(3)
) of 20 brains have a mean of
1064.1cm^(3)
and a standard deviation of
122.1cm^(3)
. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significarly high. For such data, would a brain volume of
1268.3cm^(3)
be significanty high? Significantly low values are
?
cm^(3)
or lower. (Type an integer or a decimal. Do not round.)
