Final answer:
Out of the given pairs of variables, alcohol consumption and scores on a driving test are likely to show a negative correlation, as increased alcohol consumption typically impairs driving performance.
Step-by-step explanation:
To determine which pair of variables is likely to show a negative correlation rather than a positive one, we can consider each pair:
School grades and IQ scores often have a positive correlation, where higher IQ scores are associated with better school grades.
Alcohol consumption and scores on a driving test would likely have a negative correlation, as increased alcohol consumption typically leads to poorer performance on tasks such as driving.
Men's educational level and their income often show a positive correlation, with higher education levels usually leading to increased income.
Height and weight usually have a positive correlation; as height increases, weight tends to increase as well, although this can vary with body composition.
Therefore, the variable pair that would likely not show a positive correlation is alcohol consumption and scores on a driving test.
