Question

The brain volumes (cm³) of 20 brains have a mean of 1094.5 cm³ and a standard deviation
of 126.4 cm³. Use the given standard deviation and the range rule of thumb to identify the
limits separating values that are significantly low or significantly high. For such data, would a
brain volume of 1387.3 cm be significantly high?
WORKO
Significantly low values are
(Type an integer or a decimal.
cm³ or lower.
Do not round.)
Significantly high values are
cm³ or higher.
(Type an integer or a decimal. Do not round.)
Is 1387.3 cm³ significantly high?
A. Yes, because it is above the upper limit separating value.
OB. No, because it is below the lower limit separating value.
OC. No, because it is above the upper limit separating value.
D. Yes, because it is between the limits separating values.
OE. Yes, because it is below the lower limit separating value.
OF. No, because it is between the limits separating values.
