Hewlett is attempting to measure spatial intelligence. He creates a special task to measure spatial intelligence and uses it along with other measures of intelligence. His data show that the results from his new task are highly correlated with other measures of intelligence, like memory and language intelligence. Hewlett may have an issue with what type of validity?

Discriminant validity

Explanation:Discriminant validity actual gives that proof that constructs which are believed to be unrelated are indeed unrelated . This means there is no overlapping in factors of a study.Convergent validity on the other side proves that the measures of the same construct both indeed shows that the construct are related as expected .

His data show that the results from his new task are highly correlated with other measures of intelligence, this means they can no longer be discriminated against this measure he is trying to establish.

true because they can bargain

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
