Explanation:

• A positive correlation means that as one variable increases, the other variable also increases.
• For a child, as age increases, shoe size generally increases (positive correlation).
• For mailing an envelope, as weight increases, cost (due to more postage) increases (positive correlation).
• However, a higher graduation rate in a city is likely to be associated with a lower unemployment rate (negative correlation, not positive).

Answer:

the graduation rate in a city and the rate of unemployment in a city is a positive correlation
