a) Finish the short letter to former president Trump by filling in the blank:

Dear Donald Trump: You have long argued that the presence of foreigners increases violent crime in the United States. But on the basis of our Chicago data, we would be inclined to conclude that if there are a high percentage of foreign-born people in a community, the violent crime rate tends to be _________.

b) But in fairness to Mr. Trump, I have to say that perhaps he was talking about an increase in the count – the overall number of crimes – rather than the crime rate. In a couple of sentences, explain this paradox: If he was talking about the counts, he might be right; but if he was talking about the rates, he is probably wrong.
