Answer:
Range: (844.9,1333.7)
A brain volume of 1348.3 cm cubed can be considered significantly high.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 1083.9 cm cubed
Standard Deviation, σ = 122.2 cm cubed
Range rule thumb:
- This rule state that the the range of data is four times the standard deviation of the data.
Upper Limit:
Lower limit:
Since, 1348.3 does not lie in the range (844.9,1333.7), a brain volume of 1348.3 cm cubed can be considered significantly high.
