Explanation:
cutive Function Test aimed at elderly individuals be a useful tool?
Using the standard thumb, we can say that any brain volume that falls outside the range of 878.6 cm³ to 1333.8 cm³ is significantly low or significantly high. Therefore, any brain volume below 878.6 cm³ or above 1333.8 cm³ would be considered significantly low or significantly high.
As for whether a Brain Executive Function Test aimed at elderly individuals would be a useful tool, the information given is not enough to answer that question. The Brain Executive Function Test is a cognitive assessment tool that measures various cognitive skills such as attention, problem-solving, working memory, and decision-making. The usefulness of this test depends on the purpose of the assessment and the population being tested. The given information only provides brain volume data of 20 brains and does not give any indication of the age or cognitive status of the individuals. Therefore, it is not possible to determine whether a Brain Executive Function Test aimed at elderly individuals would be useful based on this information alone.
