The brain volumes (cm) of 20 brains have a mean of 1091.2 cm and a standard deviation of 127.6 cm. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significandy low or significantly high For such data, would a brain volume of 1396 4 cm be significantly high? Significantly low values are cm or lower (Type an integer or a decimal Do not round) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.) Is 1396 4 cm significantly high? OA. Yes, because it is above the upper limit separating value. O B. Yes, because it is between the limits separating values OC. Yes, because it is below the lower limit separating value. OD. No, because it is between the limits separating values. OE. No because it is above the upper limit separating value. OF. No, because it is below the lower limit separating value.

Transcribed Image Text:The brain volumes (cm') of 20 brains have a mean of 1091.2 cm and a standard deviation of 127.6 cm 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 1396.4 cm be significantly high?
Significantly low values are cm or lower.
(Type an integer or a decimal Do not round)
Significantly high values are cm or higher.
(Type an integer or a decimal. Do not round.)
Is 1396 4 cm significantly high?
OA. Yes, because it is above the upper limit separating value.
O B. Yes, because il is between the limits separating values.
O C. Yes, because it is below the lower limit separating value
O D. No, because it is between the limits separating values,
O E. No because it is above the upper limit separating value.
OF. No, because it is below the lower limit separating value.
